The clock is ticking down on the summer so despite the heat, we are trying to fill the last moments with fun. On Friday, we headed back down San Antonio and the GameCenter in SeaWorld. I think it's fair to say that the kids were pretty happy with the experience.    And because I can't stop myself, here are a couple of short videos.That's my Sunday in one of my favorite borrowed cities -- San Antonio. Check out other cities with my friend Unknown Mami.
