In the '70s I raced a couple of times on the San Diego 333 1/3 meter track. It was pretty new at the time, and nice and smooth. Also at the 250 meter track at Encino, which was a lot steeper, and bumpier. My "track bike" was my road Paramount, stripped down appropriately, with 2 single cogs instead of a freewheel, one serving as a locknut. IIRC, my quick releases caused some debate, but since I positioned them pointing forward on the rear, and up and back on the front, they let me slide since they couldn't catch anyone else's wheel. No brakes, of course.

I found riding on the track to be an absolute blast! And even though I wasn't into mind-altering substances, riding at night under the lights at Encino was pretty trippy, especially having my shadow catch up to me and shoot out in front of me as I passed under a light, along with everyone else's. I won my points race heat, but got boxed in at the final.

I also rode around the 400 meter Marymoor track in Redmond in the '80s but never raced on it, as my sprint was gone by then due to a knee injury Just tootling around it was not the same.
