Campgems,
Good post. Restraining planes is definitely something everybody needs to do. Many people try a lot of different ways to hold back their planes, some expensive and some not. I use a very cheap one, and in my opinion it's one of the better ones. A tent stake and piece of rope. Cheap, simple, reliable, and easy to use!!!!
When an engine is running the area in front of the plane should be totally off limits. People need to start thinking this way so that it becomes habit. It only takes one thrown prop to seriously injure somebody.
