The Oak was dead about 3/4 of the way up. That one was 45 footish. We also took down a double maple (2 trees that were 1 at the base, split 4 feet up, and grew big, full separate trees) that was around 60ish feet also. Both maples were alive and well. They were in my way for my driveway/parking area.
Bring a trailer, friend, saw, or something to load the big stuff with. If previously arranged I may be able to get a skidsteer on site to load the heavy stuff.
