Well some numbers I heard were 30k a month for lease and electric alone. 3-5k in fuel in all the track vehicles a week and a half a million in equiptment in track concessions and track prep Nevermind 50 plus employees and insurance that kicks in if you open the gate that must be paid, rainout or not. Nevermind ordering tens of thousands in food and drink that some like buns will mold if you can't sell em in good time.

Im sure this varies probably a lot from track to track.
