Okay, I saw beaches, landmarks, amusement parks, and Texas... San Antonio! The only thing it lacks is a beach... but Galveston Bay isn't that far away. There's a huge waterpark/amusement park just north of San Antonio (New Braunfels, I believe is the name of the town). Of course San Antonio offers the Alamo and River Walk as well as a World's Fair tower that is SUPER cool. I spent a day in San Antonio as a day trip from Houston and had a great time... I've always wanted to go back and now that I'm a mere 5 hours away can't ever find the time to go.
