The wind drowned out my commentary over the river, but watch for the train:
Had you warned my your route would take you through Vicksburg, I would have recommended an eatery or two (with unusually cheap but good seafood). Oh well. FWIW, the railroad track (which is either Kansas City Southern or Norfolk Southern - I can't remember which) goes THROUGH the top of the bluff under the welcome center that you pass as you get on the bridge westbound. On more then one occassion as a kid, I sat up there with my lunch and watched the trains rumble benneth me.
I want one of those flips!
