When I was out at the hangar this weekend, there was a lot of activity at the hangar next door. The owner had decided to take advantage of the warm weather to either fly or run up as many of his aircraft as possible. He has quite the collection in there - Challenger ultralight, Citabria, Pitts S-2, 450 Stearman, Ryan PT-22, Cessna 421, Beech 18, clip-wing Harvard with a geared engine and an L-39 (which is still waiting for all the proper paperwork so it can fly). Plus a very fast boat, with almost as much horsepower as all the aircraft combined.
