San Antonio is such a quick drive from Houston. I went this weekend, and felt like I was so far away from everyday life. It was a nice break, and it really got me in the vacation mood for Boston. We didn't stay here, but the Menger Hotel was built in 1859, and is really a beautiful place. I enjoyed a margarita in their bar Saturday evening before dinner.
I also took a ride on the zoo train, always fun. It's nice to feel like a kid again.
