Just one question.Our 7th USA road trip coming up in April. Fly into Houston, drive 30 minutes, drop bags and go out. The next 2 weeks will be driving out of Texas into Louisiana and Mississippi. The trip is built round the Angola State Prison rodeo, where the Prisoners are in the ring with the Bulls, our second visit and worth the $15 ph., for some reason no guns are allowed and er, lock your car doors. The rest has no itinerary just seeing the real America without the tourist traps. Hardly book a Hotel in advance as there is no chance of not getting a room.
WTF do you want to go to Mississippi for? It is the poorest state in the nation. It has two good things going for it though.
I-10 west to Louisiana, and I-10 east to Alabama
