REALLY-REALLY bad idea. This has all the earmarks of a false flag operation by the anti's. I can hear them now that all the "Bubbas that go to gun shows just to swill beer and trade unregistered guns." Playing right into their hands. Also the above comments about a back door way to shut down gun shows.
Contact your State Rep and politely request that they ask TABC what is going on. Also contact TABC on their request for comment.
