I doubt that at least with the bikers. Most bikers just want to be left to do what they want without anyone bothering them. That is what they were doing here until the muslims decided to f*¢k with them..when you do that it tends to be done back to you in spades.
Many years ago as a 14 year old I went camping at a place called Bass Lake on I think Memorial Day weekend.
2500 Hells Angels and hangers on showed up like they do each Memorial Day and Camped and drank and played and danced and raised hell and had a grand old time.
When they left, their campground was cleaner and better then when they arrived.
And GOD help ya if ya messed with any of em.
