Even today not many use the safety lines. I’m scared to death of heights, takes everything I have to hang stands, take them down and even climb up and hunt them. I suck it up and do it because I love to hunt, so it’s easy for me to take every precaution and I pretty much hug the sap outta trees on my way up and down anyhow, my son isn’t afraid of the heights so I make sure to stress the safety lines and harness as much as I can. Seems like a no brainer these days.
