I think you would have to be nuts, any kind of training needs structure unless you can 100% trust the people your training with and when its a giant meet and greet that isn't possible.
And excuse my ignorance I am from Canada and the states each seem pretty small but isn't Meletich out of Iowa? That was once THE place to train with alot of great fighters coming through those doors.
