Since you have been thinking about anything a few decades, I suggest the following.
You do not need a club to get into r/c sailplanes. You do not need an instructor to learn to fly. You do not need the AMA to learn to fly. You do not need insurance to enjoy flying.
To learn r./c e-sailplane flying the first thing you need to do is do some reading and pick the right sailplane. While doing this, drive around your area looking for open recreational areas. And review in your mind which friends you have who might have a little open space and not a lot is needed. Ask your friends if they have any relatives or friends with a little.
If you would like to discuss this, it would be best to do this by e-mail and not on an open forum such as this.

E-mail me. I will be happy to help you.
Good luck, regardless.
