Within a week, I will embark on a very long trip, Houston to LA. I can obtain maps of the trip from randmcnally.com and mapquest, but I would like to know the route other people have taken and some pointers to help me out. I will be sleeping in the car when Im not driving so keep that in mind. Also, if the grand canyon isnt too out of the way, I would like to see that as well, otherwise leave it out. Let me know please.
