I had the same thought. :) I don't know what they're doing now. (I saw it when my mom led a Cub Scout pack, decades ago.)

If you wanted to organize some competitions in your city, the track I saw would be easy to build. You might want to design it to break down for storage in someone's garage, and to fit in the back of a couple SUVs. Maybe get city approval to host events as a block party or at a park. Or pre-arrange to donate it to a parish that hosts Scouts and has room to store it and occasionally set it up in their school gym or coffee&donuts hall.

Today, you also have more RC vehicle competitions, and (over-media-ified) generations of battling homebrew robots.
