I know a very nice intelligent guy who two years ago bought an old two place tube and fabric glider from a glider club where he had flown it. He bought a T-hanger at a different club to keep it in. The annual expired before he flew it. He took it to a local A&P IA who found damage from some hard landings. The repair costs were 2X what he had paid for the glider. The glider sat for a year. His hangar is now for sale.
