I'd say this is a big reason you haven't seen a tour stop in Charlotte NC for the Pros.
SW Michigan too. A legendary local TD has discussed NOT offering pro divisions because it's not worth it...and they collectively complain more than the AMs. And I'm talking about local B and C tiers.
Trying to get the $12000 added plus other expenses for a DGPT event so you can possibly break even doesn't make much sense for most of us.
