Looks like around a hundred dollars at Summit Point on a weekend. I did this year before last with the Richmond Z Car Club as part of their "Fall Foilage Cruise". They were able to get it so that we could all take a few laps around the Jefferson circuit in our Zs after the track had closed down before we karted which was actually really cool.
We'd need at least 8 people willing to spend about a hundred bucks each on Karting to make it happen from what I can tell.
To start how many would honestly be willing and commit to do that?
