For those into harvesting your own green lumber, the 17 episode BC Faller series has a lot of good information on felling, bucking and limbing trees (using chainsaws). One thing of note from this series is that this is a training series for professional lumberjacks. As such, it uses a different notching technique to preserve the most wood on the butt portion of the log. Lots of good info on chain saw safety, as well as safely dropping trees and safely bucking them into logs in less than optimal situations.
Although I have dropped a lot of trees over the years, my chainsaws sometime now sit for months between uses, coming out mainly to clean up storm damage. These videos are a great refresher on the things to watch out for to get the work done without injury to yourself or others. With the storms we have had lately, might be a good time to "brush" up on the subject.
