I went back to the blow downs to see what was down out of sight from the road. I found two shag barks a little less than 20" in diameter, down but not dead, still had green leaves. I think I can handle them better than the huge hickory I first focused on.
I checked out the huge hickory close up and found it was much bigger than I first thought, possibly 30". In spite of it's giant girth and length it only has one straight 7' cut then doglegs back and forth to the first limb.
I was going to cut them this morning but the temp is going to be 95 around noon so I will wait for a cooler day.
