like everyone else said, location and cover...

if i cant find cover, im going high...

but it seems mannnny trees in my area start to have good cover right about 20ft which is where i like to be...only been a few times i liked the location of trees that had no cover and simply climbed as high as i could....

my favorite spot is difficult...its in a saddle but the only trees that put me in the middle of the action put the deer at or above eye level when they first come off the hill into the saddle...the only thing that saves me is the tree i climb has cover and i can get a couple feet higher, and the trees around and behind me have cover..and i keep a tree or 2 infront of me...still have to be careful about fidgeting...and this year i found deer using a different area sometimes just outta reach...may have to revert to a lock on in there next year...
