Haha Hells Angels have a chapter here in Madrid, wouldn't dream of itI don’t do it myself for the simple reason that I don’t want to punch any holes in a 1500 dollar jacket. But I don’t see any problem with doing it. I would think in the event of running into someone who “earned “it , they would probably take it as a compliment. Like being famous. Just don’t try a hells angels patch. That’s a whole different ballgame
