Back in the day, Bob Klatt organized an amazing PBA Regional in the Twin Cities that actually turned a profit while offering solid prize money.
Klatt did it with a ton of work securing sponsors and producing a huge pro-am.
Obviously, all the effort in the world might not produce that everywhere, but I always referenced Klatt when someone would ask me about putting on a Regional.
Al-Mar Lanes is a current example I could point to, with the PBA50 Regional it puts in between events of the PBA50...
