it's a difficult choice between minnesota, colorado, montana, idaho (along us95 and i-90), i-94 through wisconsin, western part of virginia, and oregon. the reason being is that those states are mostly green all year round. not a big fan of freezing temperatures or the stuff that's below 0º. going through either of those states are worthwhile regardless of the time of year. the twin cities, st. paul and minneapolis are on my top 5 of favorites.
