They're there. But the fans are the customers. If they are not showing up, the administration isn't selling something to them worthy of showing up to which means they have to continue to brainstorm until they do get people to attend.
Just a decade ago, the venues were a lot more full than they are today including the fund raisers (preseason RCAF Cypress Bayou Casino event was always packed but they stopped doing it). I can't tell you how many fans I talk to in the street that say the administration does a poor job engaging with them. And these are people who give to RCAF and go to games.
Improve on communication, create events surrounding the games and make sure the quality matches what's being paid for, and the most important part.don't stop promoting because people don't show up once. We have a habit of doing that with fund raisers. They do one event, and it's poorly attended so they stop. Keep on doing them (watch parties, presentations, a bowling night, etc.).
