Sorry you walked into a family fight at wormingford, Buttino! and Thing, you always have a moan about gliding clubs....they are all different, my dears. But the difference between a gliding club and a power flying organisation is that we do get to know each other very well and make friends (and enemies too, just like your family!).....
Flying power you don't have to spend any time at all interacting with other people, just do your own ....thing! (oops, sorry! couldn't resist!)
