be smart eliminate the screw in treesteps, they can be very dangerous as my cousins friend out a few years ago. He was inserting some steps so he could hang his stand for the season, well about the6 step up, it breaks and he slides down and cathes his leg/groin on the next step and got a nice gash and stitches to go along with it. Please be careful. I recomend Climbing sticks along wiht a good climbing harness.
