My wife and I went Friday afternoon. It was fairly crowded with people while we were there. Pricing for most of the vendors seemed more reasonable than past shows, and there was plenty of ammo available even if much of it was a bit higher than the LGSs I frequent.
There was a vendor there I hadn't seen before (Eagles Soaring) who was selling 9mm FMJ reloads for $10 OTD. Their website lists it for $12 per 50. They had an ample supply of various ammo, and are located in Greenback per the label on the box. The wife bought 100 rounds to try it out.
There were black rifles and parts everywhere and the prices seemed similar to LGSs. This is a great time to be in the market for an AR.
Unfortunately, I didn't get to look around as thoroughly as I normally do because the wife was getting hungry and rushed me a bit.
