I love 60-70s era bikes.
The glory days of real choppers and those outrageous “sparkly” king and queen seats with the 4 foot tall sissy bars and big metal flake paint jobs.
If you have Netflix, search for “biker” and lots of the old exploitation movies show up like Devil’s Angels, etc.
Study the bikes and you’ll see a lot of Limeys.
In early MC culture, Brit bikes were considered entirely acceptable.
In some clubs, they still are.
Another bad experience occurred in Seattle. There is a trail around one of the lakes there that used to be a logging railtrack, and while a lot of of the bikers say, "On your left," or ding their bell when they race by you, some of them don't. When one of them literally brushed by me (at 25 mph), I told him loudly that he was a synonym for human rectum. He didn't come back to challenge my assertion, but I was ready for him.
Good ones include bikers making extra effort to stay out of the way, waiting at stoplights and crossing in the crosswalks (as opposed to getting out in traffic, pretending in their little helmeted head that they are in the same league with an F-150), and using hand signals.
Maybe along with all the 'safety' laws we should have one that allows one day of open season per year....
