RE: How many use tether lines while climbing?
Not at first but when I get to a certian height then I'll hook my lineyard to the tree to be safe.
Years ago when I first got in to bow hunting I climb up to my stand without hooking up and took a twenty foot fall hitting every branch on the way down.
My whole entire left side from my ankle to my shoulder was hurting , I thought I had fractured a rib cause I couldn't hardly breath.
Even though there was bones broken my friend still had to help me out of the woods , lession learned always use your safty harness.
