San Antonio! Any hidden attractions and things to do?
Go to San Antonio this weekend with my wife and baby for our 3 anniversary. We have plans, but I know that all suggestions you might have something to do in the middle of summer with a baby. We plan visit Schlitterbahn, the Dallas Cowboys training camp, the tea plantations up the river, and I would like some more suggestions. I thought that Hot Six Flags or Sea World for us at this time. Thank you pour votre aide.
Well, it is the Natural Bridge Caverns and Wildlife Ranch, the Tower of the Americas, Ripley, even if you do not Aventura, San Antonio Zoo, one of the countries largest and top ranked Zoo, the Witte Museum, Market Place, the IMAX theater, mini golf, and many other parks and museums! I currently live in San Antonio and I just wanted to note that the temperature reaches 100 degrees every day! Make sure to pack sunscreen! 
San Antonio is full of adventure and fun. I hope you have a wonderful time!
