Back when I was a kid, 150 years ago, The roller derby used to be held at Civic Auditorium in the Civic center. My friends had an aunt who worked for the city and would get free tickets and give them to us. It was a regular friday night event to go to the Roller Derby. You are right the players and fans were all low life. But for we boys it was wonderful. The gals were always a lot tougher than the men.
