Not many, Greg, at least close by. This one is twice a year, June and November, a grass field, and about 25 miles away. It is a small club called the Central Mississippi Light Flyers, and we have been going for close to 7 years I guess. They have ultra lights, sailplanes, homebuilts, antiques, classics, biplanes, and other small civil aircraft. Occasionally a war bird. Usually 35 or so show up. They ride kids for free, and have a chicken or fish lunch.
I thought for several years I would take a sailplane ride, but that went away for awhile. Now, I think in November I will see about one. It won't be free, but that is ok.
Google CMLF, and you can check them out.
