Other suggestions would be to ask others at your club if they know of clubs that cater to crowds closer to your age or use a dating site.
SwingLifestyles lists 290 matches between the age fo 21 & 27 on within the last month in the Dayton area (w/in 50 miles).
Swapper lists 1972. I agree that it is more difficult to find a younger crowd, but they are out there. We've met two couples recently (one was 21 & 23 ,the other was 23 & 30 ) in just the past month but we did it online.
