RE: How high have you been ?
I have gone as high as 45ft several times while rifle hunting, in order to see as much of a cut-over as possible. The highest bow stand I ever had was 34ft. I try to keep my stands from 18-25 with most of them around right around 22ft. I do have one this year at 30 ft but that was simply where it had to go if I was going to hunt that particular tree.
