My state map is rather boring since I've been in all but three states and that adds up to 524 EV. However, here's my county map. Red counties have been my places of residence, blue are places I've stayed the night, cyan includes visited destinations, green are places in passing including meal and gas stops, and yellow is airport only.
My states of residence total 149 EVs.
Wow, that map must have taken a lot of time. And I'm impressed with your memory. You really remember every county that you drove through, and counties in which you spent the night? And you certainly have scoured Iowa pretty thoroughly. Do corn fields particularly fascinate you? And what did you visit in Madison County, Iowa? The covered bridges and John Wayne's birthplace? If so, you saw my great parents' historic home next to the birthplace to the west on John Wayne Drive, and drove by the farm, if you drove south from Winterest on Clark Tower Road (the farm is off to the west as soon as you start going down the hill to the Middle River, and you go right through the middle of the Cunningham field right after you cross the bridge over the Middle River going south, with the balance of the farm to the west right after you cross the bridge over the Middle River, with the Middle River its southern boundary (the Middle River bends south after you cross the bridge, before turning east-west again as you move to the west).
Does training count? I've taken the train from LA to Chicago as a little kid. Anyway, I've been to every state now except ND and Alaska. I finally got around to going to Maine last year (which I loved).
