This morning's Texans training camp ticket giveaway didn't work out so well. After failing to get through all day, I logged on late this afternoon and was able to get tickets to the Friday, August 3rd session, but all the weekend sessions were sold out. Now, however, it appears that only the August 3rd session is sold out; the other five (5) sessions are open and the site worked smoothly when I tried it.
If you go here now, you should be able to get tickets to any of the five (5) remaining open training camp sessions. If you had problems this morning getting through, give it a whirl again.
