Took off early yesterday to go scouting for more Osage Orange... Didn't find any but ran across a giant sugar maple I've known about for a long time and a big mulberry that's been hidden from me for close to 20 years. The maple is big... Really big. The picture doesn't really show how massive it is. The limb coming out is at least 12". The mulberry is a good 20"+dba I had a stalker while I was walking around too. I did take a briar ax with me and took care of some annoying vines trying to take over a few trees... Allot more to tackle over the winter.
Looks like you have your work cut out for yourself there. Lots of limbs and on a hillside. Be carful.
