Do they still count as a "gang"?

Elanna and I were in Eureka Springs, Arkansas this past weekend for her Uncle's wedding. The wedding was very nice. It was supposed to be an outdoor wedding but, of course, it rained. That makes 3 outdoor weddings I've been too that had rain interfere. The wedding wasn't the excitement of the weekend though. Apparently, Eureka this past weekend was also the location for the National Hells Angels convention. There were literally hundreds of bikers everywhere. There were also were also lots of police, lots of police, FBI, State Troopers, AT, DEA. Elanna said that at one point it looked like they had raided the Hell's Angels hotel. An officer in plain clothes was holding what she described as a "very large rifle" in the parking lot. They also kept buzzing the entire town with helicopters, I guess to let everyone know they were there. Other than one slightly drunk biker that we encountered at the Grocery they seemed pretty tame to me. A lot of them looked like they had been in the Angels since the late 50's so I'm not sure how rowdy they could actually be.
