I agree that bikers, like many things in life, aren't always what they appear to be or what their reputations would have us believe. I only know a few personally, but they all have a humanity that counters all those stereotypes. Doesn't mean there isn't some truth to their reputations, but there is very often more to the story.
In fact, when my car broke down the other day, a biker stopped to make sure i was ok, and try to help.
