1) If you have a large Oak tree - hoist the engine from the largest branch.


Even then you can never tell. I have several 70' oak trees and one had a nearly
horizontal branch up about 20 feet. The branch was a good 10" thick. Many times
I pondered how I could get some ropes up there for a swing for the grandkids.
One hot summer about 3 years ago, I was walking in the back yard and heard a
tremendous splitting noise, and the entire branch hit the ground with a crash.
