Well MM, that tree was certainly worth the effort. Lots of good firewood there. I am surprised a seasoned wood cutter such as yourself doesn't carry some wedges. One would have made the root cut easier as you could have gone through it in one cut.
Great video! I love working in my woods and collecting downed firewood. I usually move pine to the sides of my driveway as a type of retaining wall and keep from venturing into the wetlands. I don't like to take down live, viable trees and only take dangerous or dead ones. I like that 3-pt box you have. Is that home made? If so, nice job. If not, where did you get it?
