Kinda weird. cause Blackhouse is not only Nog's gym in Florida but also in Brazil. And if you say GSP is under Greg Jackson's gym which I think is in New Mexico, then why hasn't GSP been there for quite some time, and he trains out of TriStar Gym in Montreal...currently with that ex USSR sniper guy Zihabi.
I'm not sure how much a camp really matters, might be more up to the gym and your team.
Team Nog looks sweet (not Blackhouse) but I don't see one guy who isn't Brazilian and I don't know Portuguese
Here is a sweet list of teams - Template:MMA Team List - Wikipedia, the free encyclopedia
For some of them it shows their facilities. Like Nova União has 5 different facilities, but they also have gyms they do promo's at where they send trainers around the world to train at different facilities.
Like it says Sam Stout fights for Xtreme Couture, but he actually has his own gym Adrenaline Mix Martial in London Ontario with Chris Horodecki and Mark Homenick. On wikipedia it says they are all Xtreme Couture, on Sherdog it says they are Team Thompkins.
One gym/crew I wouldn't want to be with is HammerHouse, who have never had a gym. They once ruled UFC and Vale Tudo (for nearly a year) but they were really just a group of fighters who trained together whenever and wherever they can.
