I-90 West to Seattle
CC, based on your profile, I'm guessing you'll be starting from FL, possibly heading up some Interstate corridor to the Chicago area, then westward. You'll be cutting right through IL/IN.
Another thing to keep in the back of your mind is the springtime weather on the Midwest plains. That block of OK, AR, MO, IL, IN is not called "Tornado Alley" for nothing. Eyes open.
