I started aviating in ATC gliders and would have liked to return to gliding,
Unfortunatly the attitude shown to me has put me off the idea.
Gliding in the UK is slowly dying with club memberships falling and no new blood getting into the sport, from my experience I can see why people are put off.
Membership is going up where I fly, and we have a lot of power pilots as members. Most are GA pilots, a few fly for BA, BMI, Easyjet & so on. Dunno where you went, maybe another club would be more welcoming?
