Not pooh poohing on your idea, I think it's great to have somewhere to race, but there is a ton of logistics to think about. What type of track first off. Off-road dirt, dirt oval, crawler course, paved on road? Are you in a residential neighborhood, will the neighbors mind 20-30 cars/trucks in front of the house? Power for charging stations? Bathrooms and such facilities? Permits from the town..lord knows they want their cut..especially up here in Mass. I believe if you build a place to race, then yes people will come race. Awesome idea and I do hope it works out. I would love more places to run cars.
