Forgot to mention, there are lots of ultralights.Not all are 103 legal.
Go to the web and sign up with the EAA experimental aircraft association.
There is most likely a chapter close to you. They will be more than helpful.
Usually have monthly meetings and seminars on different subjects pertaining
to interests airbums like us need to know. Be sure to check out fixed wing trikes,
powered parachutes, there are back pack mounted, and the ones that are like a
three wheel go cart with a parasail. Buckeye builds a nice one. Also gyroplanes.Even if these aren't what floats your boat, they are fun to see. I remember the first time I got to see a gyroplane fly (bout two years ago) Holy Cow!
Pretty Cool! Sorry for the long post, seems I'm an airplaneaholic...
