I am sure bikers are like any other group, some are good and some are bad.
I have been on a motorcycle once in my life. A friend who was in the Navy took me to Mirimar to watch the Top Gun pilots fly years ago.
He warned me to be brave and not make any sudden movements because some people in cars would target bikers. I had no idea what he meant but some idiot in a car actually threw a carton of milk at us! We had in no way done anything to that person! So I am sure just as there are drivers that are horrible to bikers there are bikers that are horrible to drivers.
One ride and you got a carton of milk hurled huh. I guess bikers might have had a bad reputation in those parts? I used to ride till I couldn’t afford to keep the bike, and never got anything hurled at me, though I did get barrelled into by a van driven by an inattentive man once.
