Don sent in a picture and video of his pull behind attachment for snow sleds! Here's what he said about the build

"Very happy I ran into your product! Ours is a pretty small project, but important to us. We are older, but active outdoorsy folks and do some winter camping. In order to do this we have Pulks (snow sleds) that we pull behind us either when on snowshoes or XC skis. We have been unhappy with our attachment of poles to sled and now have used your product to achieve a more stable connection which we will be testing this winter. I have attached a video and still showing the attachement. It allows much flexibility in the vertical plane ( read up and down rises and hills --- and snow banks:)) and minimizes motion in the horizontal plane. Still enough to track well behind the "pulker" especially since there is still considerable flex at the harness attachment." - Don
