Bikers are usually ok as long as they are not gang members.
The gang members won't give you grief as long as you stay out of their business. Start playing macho ass and all bets are off.
Most patch holders will correct you if you call them a "gang." They'll tell you, in no uncertain terms, "we are a club, not a gang." The FBI doesn't see many of them that way though, but there are good clubs, like the USMV MC which originated there in Florida.
I've been riding motorcycles myself since I was 9. I've owned 7 motorcycles in my life, 3 of which have been Harleys, the last of which is my 2006 FXD35 that I bought new. I'm also a retired Harley Davidson Technician, among other careers, and have rubbed elbows with just about every club there is. I was a hang around with the Vagos while I lived in Reno for almost three years. Still have the Vagos Supporter cut. I just ride for fun nowadays, and don't want anything to do with any club, good, bad or in between. To many damn rules, club politics and mandatory bull shit for me.
