sounds like you ran into what is known as a "biker gang". serious a**holes, and I am glad you took appropriate care of them.
BTW I own a "squid", a cruiser and a dual purpose. [almost] all the a**holes on bikes around here are on Harleys. serious jerkoffs. I'm in Milwaukee.
ride safe.
I don't know what to call them really. What I do know is that they're becoming more common, and more troublesome, and they universally have a problem with guys riding cruisers. I need to remind myself that there are a lot of good people on sport bikes, because that's what they like to ride.
