Karting at Pine Brook?

Here is a most unusual photo taken by Dave Innes, and sent to us by Gary Mondschein: A 1960s go-kart on a victory lap at Pine Brook.

This photo appears to date from the late 60s. Early enough that there is only a roll bar on the kart (New Jersey required the same safety standards for karts in those days as it did for all other racing machines), and late enough that the infield ripple strips are in place.

Kart racing never took root at Pine Brook, despite the track's compact size that would seem to lend itself to the tiny machines. Among the reasons is that kart racing never took root in New Jersey back then, in part due to those State regulations.

Now, Gary, can you find us a photo of the one-and-only flat-track motorcycle race that took place at Pine Brook?
