"Frag Swaps" are actually coral shows these days. Ours is The Pittsburgh Reef Aquarium Expo. We don't market it as a Swap as we find newer people thought that they needed to bring things to "swap". That being said I've seen a ton of people trade coral at shows. Most of the time I see it prearranged. This thread was posted an hour after the event started so not sure how many people were looking at their phones or brought extra coral with them to Swap.
