The Southwest looks exciting. I might plan on going to the Grand Canyon, the Alamo, the Gulf of Mexico, and San Padre Island. I will also want to go to see the Native American Reservations and Tribes. The Southwest has a lot deserts including the Sonoran and Tule Deserts in Arizona which have different kinds of cacti including the saguaro cactus.
I also want to go to see the Painted Desert in north central Arizona. I hear that the sand is red and yellow and it looks like it is painted.
