Two additional county splits in the southern part of the state (Indian River and Palm Beach) that I really don't see how to avoid, although proving this is long and cumbersome. (I can prove that at least one additional county split is utterly unavoidable, though.) Or you could do a non-consecutive district made up of Saint Lucie, Highlands, and part of Broward. That would avoid any county splits.

Virginia
With recourse to the rules in the initial post, I'm treating the city of Fairfax as part of Fairfax County (in order to not be forced to put it into D1. I could argue that Arlington, Alexandria and Falls Church are also in Fairfax County, and therefore there's no additional county split involved, but that wouldn't, like, actually change the map).
I'm ready to admit the Virginia Beach - North East Virginia district is weird, but the alternative is worse.

I'm going down into Georgia to knock down my last game...

Cobb County can't stand alone nor be paired with any neighbor. That I've actually split the offending county rather than a less central one around it is novel, I'll admit.
Populations can probably be balanced better, and I invite anyone to do it. With Georgia's approximately seven million counties, any such redistricting project quickly turns into mechanical calculator-pumping...

If this were attempted in IL, it would fail at the State Supreme Court which has ruled that there can be no more than 0.5% deviation from the ideal district population. However, if these rules were adopted by Congress to be applied to the states then that decision could be avoided.

I don't know why I waited so long to post this, but shortly after you started this thread I went through a fairly exhaustive process using Microsoft Excel and Sort Commands to separate and get rid of some of the plans with discontiguous districts and came up with the closest plan in terms of population parity that follows your rules.  If you count Hancock County as being contiguous to Knox County, which borders it by the waters between Stonington and Swan's Island in Hancock County and Isle Au Haut in Knox (and Isle Au Haut is connected to Stonington and only Stonington by ferry and is in a state Senate district otherwise entirely in Hancock County, and there has been since the 1990s reapportionment a state House district including Isle Au Hout and a couple Island towns in Knox County closer to Rockland as well as several towns in Hancock County but none of Waldo County, so there is some precedent for crossing that boundary without having a mainland connection), if you count that, than the closest plan is as follows:

1 York, Oxford, Franklin, Somerset, Kennebec, Waldo, Penobscot and Piscataquis Co.s 637,400 (.9999 of ideal ME CD pop.)
2 Androscoggin, Cumberland, Sagadahoc, Lincoln, Knox, Hancock, Washington and Aroostook Co.s 637,523 (1.0001 of ideal)

Here's the HTML address of a map of that plan, with district 1 in green and district 2 in gray:

http://img128.imageshack.us/my.php?image=canthelpit1uw7.png

If you don't count Hancock County as contiguous to Knox County, than the closes plan following your rules is as follows:

1 York, Cumberland, Sagadahoc, Lincoln and Kennebec Co.s 638,298 (1.002)
2 Oxford, Androscoggin, Franklin, Somerset, Piscataquis, Penobscot, Waldo, Knox, Hancock, Washington and Aroostook Co.s 636,625 (.998)

Here's the HTML address of a map of that plan:

http://img128.imageshack.us/my.php?image=canthelpit2ou8.png

In the 2003 congressional redistricting, the Maine Supreme Judicial Court adopted as its preliminary plan the plan shown right above except that the municipalities of Bremen and Monhegan plantation (Monhegan Island - I had a friend from the daycare I went to in first grade who moved there) were in the 2nd district.  But Bremen only bordered Knox County by water (Monhegan Island is connected to both mainland Lincoln County and Knox County by ferry, although it is surronded by non-township territory within Lincoln County which would have had to have been in the second district).  A Democratic lawyer mentioned that in the public hearing before the supreme court, and the Democrats also I believe got a lot of written testimony from Knox County residents who said they didn't want to be in a different district from their "sister county" of Lincoln.  The Democrats actually stated that they preferred a plan the Republican party had drawn, with Waldo County going to the first district and a majority of Kennebec County including Waterville, Winthrop, and Gardiner going to the second - basically the first hugging the coast up to the Penobscot River with a small protrusion inland.  In the end, Democrats got a plan close to what I read on a conservative web site was their original plan, but which they might have abandoned because the federal courts seemed to be getting ever more strict about population equality and the Republicans had proposed a couple plans they really didn't like that had only a 1 person difference in population between the districts.  The Republicans were quite supportive of the Maine Supreme Court's preliminary plan, however, which had a 41-person difference in population between the districts.  The plan some on a conservative web site were knocking the Democrats for had only a 13 person population difference between the two districts and only moved 9 Kennebec County towns from what was then the first district to the second.  The final plan adopted by the court had the second district exceed the first in population by 21 people.

I don't know why I waited so long to post this, but shortly after you started this thread I went through a fairly exhaustive process using Microsoft Excel and Sort Commands to separate and get rid of some of the plans with discontiguous districts and came up with the closest plan in terms of population parity that follows your rules.

How do you do this with a spreadsheet?

If you generated all combinations of 8 counties or less (the district with fewer counties has to have 8 or fewer counties), and 3 counties or more (you need 3 largest counties to get enough population), there are 39,066 possible combinations.  Most of these will be way off on population.  And many will fail contiguity tests, either for the district or its complement.

But that seems a lot of districts to generate with a spreadsheet.

[Kevinstat]

I actually plugged in all 2^15 combinations of counties into districts with York always in the first district, sorted out combinations with Oxford and Cumberland in the 2nd district, then with Oxford, Androscoggin and Sagadahoc in the second, all the way to sorting out all combinations with Somerset, Kennebec and Lincoln Counties in the 2nd district and putting back from my map knowledge the combinations with the 1st district contiguous consisting entirely of counties east of that line.  After still having most plans be discontiguous, I used similar sorting methods to get rid of plans with Cumberland surrounded by 2nd district counties and got rid of another large group of discontiguous plans as well.  I originally hoped to determine how many plans were better than the one "the Trond" came up with, but gave it up when it took so long to just find the closest combination of contiguous (by land) counties.  Yeah, it was a lot of work, but I wanted to be sure that I had come up with the closest plan satisfying the Trond's criteria.  I had planned to post the closest to equal division of the counties into districts totally ignory contiguity, but forgot to check that before I started deleting non-contiguous plans and don't want to go through all that again, although it wouldn't take that long for me to learn what that plan is (and the plan with just one district contiguous, which I think was the third closest among all possible combinations - I didn't do any deleting on my first try and didn't even delete 1/2 of the 2^16 combinations, but I gave that up when I didn't find a "land contiguous plan" my second or third page).

[Kevinstat]

But that seems a lot of districts to generate with a spreadsheet.

My spreadsheet has exactly 2^16 or 65,536 rows, so before I came up with the idea to fix York County as being in the first district, I had to initially start the rows on collumn 1 before I used the sort command to separate and then get rid of the plans with the second district greater in population.  Holding down the shift key and using the "END" button was invaluable.  I wouldn't have been able to hold my finger on the mouse for some of the groups of collumns I wanted to delete.

[minionofmidas]

I know why I didn't find the first of these maps - it never occurred to me to search for a combination that separated York and Cumberland.
I'm not sure why I didn't find that second map - although it hardly matters as my map too is within 1%, so I didn't have to prove whether there were any better maps.
