That is a room in a church in Garland. We had some details outlined here on our site:

Fortunately, one of our members is associated with the church and gives us the room to meet in for free. I'd estimate we had 100 people there, and easily over 1000 frags this time. I don't count them like I wish I could (as we all know I love to track numbers), but there is no doubt we had that many frags.
We have two Frag Swaps a year now. The November one is the one I prefer, because the weather is cooler, but the members wanted a second one so here we are.
The room got hot with so many people there, which bothered many unfortunately. Our raffle was fun, as we had three different types this meeting. Each person that brought at least 10 frags got a special raffle ticket, and the one that was drawn got a $50 gift certificate for the LFS of their choice. Then we had two drawings for a full registration to MACNA, and finally we had our regular raffle. Due to the fact we were surrounded by livestock, I didn't focus on getting livestock (fish typically) for the meeting. Instead, I acquired 5 Maxima clams, and then 10 frags of zoanthids, as well as a bunch of useful drygoods (grounding probe, pH calibration solution, Prime, Chemi Clean, Purple Up, Phosbuster Pro, thermometers, cleaning magnets, etc) - that way no matter how long you were in the hobby, you'd find something you could use.
Some members donated some frags to the raffle instead of taking them back home, which is always appreciated. One person donated a brand new 20lb CO2 tank that was already filled up! Another donated a tank, stand and canopy to a good home.
We combined the Frag Swap with our club's Annual Meeting, which we won't do again. Everyone is simply too excited to trade and buy/sell, but somehow we were able to get the election done and now have three new Board of Director members to fill those empty positions.
