Insurance, EMT crew, fire safety crews, corner workers, etc, etc. You’d need all that. Plus food vendors and janitors to clean the bathrooms. You’d basically be running a track, and that these days isn’t cheap.
If such kind of money existed in my bankroll it’s be enough that I’d buy it for myself and tell the public to fuck off. Be like Cartman from that episode of southpark where he buys the amusment park.
