Slightly off the subject but I'm always amazed at folks who will buy a fine piece of machinery (airplane) and then tie it down outside and let the weather and sun beat it to death. Often they apparently lose interest in the subject and it sits on the ramp or in the weeds for years and never touched. I can think of several right now. My father in law who was a good farmer never left his machinery outside. Once it was done for the season it was cleaned up and put away under shelter. I was just looking at a Cessna 150 yesterday that I don't believe has been moved for 10 years.
