Some of us remember those days. First board I rode on did not have edges had three fins bolted on like a surfboard. That was the cutting edge tech at that point. First one I bought did have full metal edges though. Was a time before internet sales and no local shops so had to drive to the Burton Factory to buy my first board.
And yes that was how people felt about snowboarding at that time. Getting yelled at for going off a jump because a snowboard ruined them.
