I've had that same basic idea too! Well, there's a xtian biker club so why not? Satanists are way more badass than dumb shit xtians! Although, I guess siguard666 makes a good point about being associated with groups like Hell's Angels. It's probably not entirely a bad idea though. There could definitely be some potential for popularizing Satanism. Another nice thing about biker gangs is that because of their reputation, not many people will want to mess with them. However, you would have to be careful that the gang in question would not exude an overly negative image to others. If I got myself a motorcycle license and a sweet hog (Maybe a Fat Boy!), I might see myself doing something like this. I'm not into tattoos though! If you like them, fine, they just aren't for me. Besides, tattoos are a bit cliché when it comes to bikers.
