As of now the NRA AM is still on (just got off the phone with the NRA). Nashville has canceled every even except this one. If anyone hears anything reputable, please post up in this thread. The NRA has a bad habit of making last minute decisions, and not giving vendor's time to react to them.
Thanks for the information! I just sent an email about this very thing this morning but yet to hear anything back. I'll post if I hear anything.
