I'm not going to post too much right now, as I just got home about an hour ago, but I am back from a quick skip over to Kentucky.
A couple of notes: US-62 and US-68 - really nice drives. GM Bowling Green Assembly - awesome! Toyota Georgetown - the picture that should be next to the definition of "large".
I've got to compile my info and such - I estimate about 2300 miles in 4 days, though I did have fun and see a lot.
