Steve Caballero's ramp in San Jose went up in the early 80s when the parks closed. Even at just 12 feet wide it was a nice ramp, providing a lot of skaters with a place to ride for a long time, off and on as the layers came and wore out. When the mini ramp craze hit in the late 80s it was cut down into a rad ramp that I loved. ALthough there are only a few photos here now, I've got more that I'll dig up soon.
