From what I heard, last year's event had a good turn-out. The airport appears to be a big advocate of light sport aviation, also hosting Gyro fly-ins. And 9F0 was an early adopter of Swift Fuels UL94 "Unleaded AvGas".
Also worth noting that Dublin is the home of Dublin Bottling Works, where Dr. Pepper originated. Word is that they will send a driver to the airport, if you want to go into town to tour the facility and museum, and visit their old-fashioned soda fountain.
I'm not affiliated with these organizations. Just hoping to see some fellow SportPilotTalk folks at the event
