Cool stuff. I had an old Aurora AFX track for years, the old style that took 2 metal alignment pins and a plastic clip to connect each section. I had been messing with them and collecting slot cars since I was a kid so I had a big collection of cars and enough spare parts to keep them working for years. I finally sold it all about 20 years ago and by that time old AFX stuff from the 60's/70's was collectible especially the cars so I got a good chunk of change out of it.
