Last weekend when we had a little bit of fresh snow, I went for a ride with a guy who lives across the lake. He giggled at me when I hooked up my DESS tether to my jacket loop.
I've always figured the 2 seconds it takes (added a big hook) is well worth it just in case you end up off your machine. Especially so when you got a 4 stroke that could end upside down at the bottom of a hill. At worst, it would save me some embarrassment. Have never had it snagged yet going through the brush and kill the engine.
Question is, do you use the "dead man's switch" on your sled??
