Is this the show that is part of the annual Texas State Rifle Association convention? If it is then the show is a great place to join or renew your membership, Join or renew there and that includes show entrance fee, not a bad deal.
I have no idea but if you give blood to the Carter Blood Care bus out front you get in for free. I decided I would rather pay $8 then be stuck with a needle and have my blood sucked away like a Vampire!
