I love cutting trees, the whole thing, felling, limbing, bucking, carting it away; just a great time and beats the hell out of gym membership.
I took down 1 pine today before the wind picked up (from the wrong direction). Probably just shy of 20" butt, I used the 16" bar anyway. Fell exactly where I wanted (all the brush at the top is within 30 feet of my burn pile) - bucked it all stove length, my neighbor has an OWBF and said he would use it. I'll haul it to the road and he can come get it with his pickup.
Just a nice day to be outside, working in a T-shirt.
