There is a precinct south of Enterprise, Oregon that is a 5-hour drive from the nearest Clinton precinct.
The "drive times" don't really make sense for remote islands, though. Monhegan, Maine (might be Stein's best precinct with a non-negligible number of votes - she got 16%) is shown as being a "55 minute drive" from the nearest Trump precinct, but there are no cars on Monhegan and no car ferry to the island.
Also, New Shoreham, Rhode Island (another remote island), is shown as 5:09 drive to the nearest Trump precinct. I think it does have a car ferry, though. And Nantucket is shown as a 10:18 (!!) drive to the nearest Trump precinct, but that seems to wildly overstate the amount of time it takes to get from Nantucket to the mainland (and there are Trump precincts right near the ferry on Cape Cod).
The farthest on the "mainland" (connected to the rest of the country by road and not by ferry) I can find is Montauk, New York, which is reported to be a 5:14 drive from the nearest Trump precinct. Problem is that it seems to be picking up a location in Rhode Island, which, while nearest in a straight line, is obviously not the shortest travel time; there are Trump precincts around an hour away elsewhere on Long Island.
maybe it's counted from Midnight and so the ferry isn't in operation so you need to wait for it?
