You know, we all have lottery dreams. "If I won $100 million, what would I do after the government took their 40%?"
I'd build a bowling center. Not to make mass amounts of money, but to give something back. Center would have 2 sides. 1 for open play, parties, and nonsanctioned leagues. It would have open lanes at all times, and a flat rate of $2 a game. Women's and senior leagues, with child care available.
Other side of the center would be for tournaments and sanctioned leagues. League shots would be fair and make you somewhat work, but that would be the cost of being on the sanctioned league side. Bigger concourse, more ball storage, automatic doors, etc. All center services would be in the middle, accessible to both sides. Pro shop would be center owned and I would have a certified coach on staff to coach up the inexperienced bowlers.
