>>2025803I highly recommend it if you have a bit of spare cash. I bought a share in a fiberglass glider from the late 80's for <$10k. A tow to 2000ft was about $60 at my club, yearly club fees about $250.
It's different for every club, but the common theme in my country is that coaching is completely free (you just pay for the tow/launch and glider hire). You're expected to get there early and help out throughout the day, even if you're not gliding that day. It's a team effort and volunteering keeps it relatively cheap.
