I think that clubs in the USA that make a commitment to winching are on the right track.

My club seems close to having the critical mass of aspiring pilots in their teens and 20's. They would turn out and fly more often if the cost of launching were lower. Yesterday one of them brought up the cost of a 'decent glider' and he was wondering aloud if he would ever be able to afford one (probably yes, especially with the trend in resale prices). But at this point in his training, the cost of aerotows is (obviously) holding him back, and his situation is typical. We have a nice stable of club gliders and great soaring terrain, but aerotows are still pricey for many.
