I don't stress wearing a safety harness just like I don't stress wearing a seat belt.... reason being.... I believe in natural selection.

If you lack the mental gear to wear a safety harness (especially in a climber), then sooner or later Mr. Darwin and his theories will leap up and bite your backside.

Honestly there have been a few deer that I wouldn't have gotten a shot on had it not been for the harness.... having the ability to swing out/lean out to get around a small tree and be held in place by the harness is quite nice... takes a while to build up the courage and trust in the thing, but it will hold!
