My current gym has none. they used to have a few, then management changed around, and I don't know what happened.
I know that when I was with CEA, we usually had a Senior CoEd 3 at my gym, and it was crazy to see who got recruited just by word of mouth. We had one kid, he was over 6 feet tall, and was a serious athlete, (not saying we're not athletes, because we most definetley ARE!) but he played about every sport, and his sister was on senior 3, and she told him to come, and he did, and he loved it. he later brought some friends and they were all naturals.
I think word of mouth is easiest in recruiting guys!
