Long story short, no animal in the woods is worth a fall which could alter your life or end it.
Today I had my foot platform on my climber get away from me. Yes, it was tethered to the seat, but the tether was old and snapped. I was left dangling from my hand climber on my forearms. I had to use my linemans belt to hold my weight as I shifted the seat portion down a touch. Then, crawl on the seat and move my linemans belt down a touch. Then jump off the seat and move it down a touch, and so on and so forth. All in all I came out perfectly fine and safe, but without the proper safety equipment my life could have changed forever this morning. By the way, this method was NOT the preferred method of scooting down a tree but a man has to do what a man has to do sometimes.
