Being a pack rat, I have all my old stuff from the 60s and later on from the 90s when I raced a lot at a track in the DFW area. I even built a track with routed slots and copper tape during the 90s. Moved and had to get rid of it but was a lot of fun to build and race on.
Here's a pic of the track. About 55 running feet I think.
Have one of these too...
