I am making the drive from Las vegas to Houston in a couple of weeks. I have NEVER done a road trip like this ever. I am 28 and taking my 6 year old son. The longest we've ever gone is about 5 hours to California. I would like to take him to the Grand Canyon, and the Alamo for sure. I am asking for pointers on "roadtripping", and places to stop along the way. I am very independent and confident that I can do this....it would just be nice for a little advice. thanks.
