That was a pretty nice track, used to drive down there from the SFV a lot. Besides the 64 Funny Car shows, once saw an F4 putting in overhead with one engine smoking, and saw some guy in a Camaro put the car OVER the guardrail along the right lane and into the grass, upside down. Wasn't even a big wheelie, just bad-outta-shape and he wouldn't lift.
Man, it was a special era when Lions, Irwindale & OCIR were all open; lotsa times we agonized over where to go. Lions usually won out until it closed.
