I’m in that general area, although not at any of those gyms. Those are all good gyms. SGA has a really nice facility that makes me quite jealous.
I have a friend whose daughter is at TAG and loves it. Unless it’s changed, I think the actual facility at RSG isn’t as nice as the other 2 and is much smaller, but they do well in competitions. I guess it all really depends on what you are looking for in a gym though. Feel free to send me a private message if you’d like.
