My best friend and I used to live near San Francisco State College, but we would take a bus and muni after school and weekends to go ice skating at the rink on 48th and Kirkham. We started doing that when we were eight until about 10 years old; that was from 1973-1975. We used to take lessons, then stay to skate.
I remember doing the hokey-pokey and harassing the boys, and I loved going into the snack bar to have hot choclate and play pong.
It's very sad to hear that area is run down now.
