Even if it would cost $1,000,000 to do this for the whole season it would only take 50,000 tickets to be sold to cover that cost. How many teams in MLB don't sell 50,000 tickets in a year? Everything after that expense is 100% pure profit.I think you are really underestimating the costs of things you think just happen for free. If the team doesn't have an exemption in place from the state, they are going to be paying quite a few dollars just on real estate tax on the land for the parking lot. That isn't including maintenance, (asphalt and repairs are not cheap) and labor to collect the tickets and clean the lot. Then there is the port-a-potties and dumpster costs. I'm sure there are other costs just to having a parking lot that one wouldn't think of until you were running it.
