Here is a photo history of club racing from the 70's.

Luf and Ted both built home tracks.They alternated race nights.
Note the faint trace of the first apexed corner.
(Luf told me the other racers didn't like the squeeze effect, so he just routed in the normal, parallel, replacement....)

They both were hired by the same plastics shop, so of course....

They were making the boss so much money, that he didn't seem to mind if they spent all their spare time playing. So the new track was bigger....

They wound up together again at (wait for it now) WESTSIDE, and, well....

And, since they had already established the tradition, and there was no more room in the shop, they needed a mezzanine....

Here are some of those old cars, and the traditional Race Night Hat....
