Cross country skiing for winter search and rescue

I took up cross country skiing this winter. The woods are beautiful in Minnesota.

Classic cross country skiing is a great workout for the whole body, is low impact and a great way to get around in the snow. A good way to stay in shape throughout the year for an emergency situation.

I think it would be useful for winter search and rescue, although the skis would degrade and lose some functionality if they were used on ungroomed trails, especially on broken ground and going over sticks and rocks.
