Day 2: ~450 miles Vicksburg to Weatherford, TX. I-20 almost as rough as I-10 & I-40. Traffic was pretty heavy but moved right along. Gas mileage on the truck getting slightly better - - over all average now up to 11.96. gas prices out here are well below FL prices - - gas at WM this afternoon was $3.46. Drove south of Dallas and only got a short glimps of the skyline through the haze.
