There's a world of difference between a club & a gang. Barry I can't see it - there are things calling themslevs clubs that are as vicious as any gang, and things calling themselves gangs that are totally innocuous or beneficial. It's all a question of what sort of image you are after. (That's just me being pedantic - no comments about the HA's...)

Hunter Thompson's Hell's Angels is great reading.

And here's a link to the man hinself, out in Colorado. His link to his local National Anthem, Sots and Sinners, doesn't work for me - but it's a great song, worth digging up.
