Love the old highways. I'm sure I've mentioned before that in my younger days I would drive Highway 41 from Tennessee to Chicago to meet up with college buddies over long weekends. Always enjoyed that I was in the middle of an Allman Brothers song.
And good God, to be young and stupid. I'm just realizing that was a 7-hour trip in good conditions. I would leave Friday at the end of the work day, and drive until after midnight to get there, then drive back on Sunday. Dumb.
