I'd like to take my son (and wife) to a Texans practice one afternoon. Excuse my ignorance, but I don't know anything about how I should go about it. Are there tickets that have to be purchased? Are there better days to go than others? What time is the best time to go? What times CAN you go? How close can you get to the players? Do they sign autographs or anything like that? I've gotta drive over an hour to get there...so I wanna make sure it's well worth the trip. Keaton (my son) would have an awesome time getting to see them practice. Everytime we drive past the bubble he says, "Hey Dad, you see that big white balloon over there? THAT is where the Texans practice." ANY SUGGESTIONS AND/OR RECOMMENDATIONS WOULD BE GREATLY APPRECIATED.
