learning how to soar will certainly expand your airman abilities. for me soaring provides the challenge I need to stay excited about personal recreational flying. always trying to go higher, faster, and farther. I would highly recommend you go for it. check out www.ssa.org
that is the website for the Soaring Society of America. They have an application called "Where to Fly" and there you can find the closest soaring site to you.
The last weekend in June through July 4 is the International Vintage Sailplane Meet in Elmira, NY. It will be a great time, the reunion of the old time gliders with a full week of flying and fun planned. I'll be there opening weekend.
