We don't/won't ride weekends so today we went to a cross country ski area nearby that is groomed and maintained by the DNR.. It's a nice change of pace from riding and of course very healthy.. The trails were groomed perfectly for the first mile or so.. We passed several "no snowmobile" signs.. At the first intersection there were sled tracks and the guy(s) decided to ride the entire outside loop of the ski trail tearing it up.. When X-C ski trails are groomed they leave two slots for the skis to ride in. When a sled goes over this grooming it wipes it out and now the skis wander and search. There are lot's of sled trails in the area and it was very selfish of whoever did it to ride their sleds on the ski trails.. So we went for a few more miles with less than ideal trails due to the sleds wrecking them and met up with a Finnish lady who quickly said "be careful, the snowmobiles have destroyed the trail".. I agreed with her and cursed the sledders right along with her.. Then we meet up with another couple and they are also angry that snowmobiles had destroyed the grooming.. They encouraged us to take down the registration numbers of any sleds we saw and report them. There was no way for me to defend our brotherhood to the granola heads.. These were nice people and purposely ski that area to AVOID the sled trails (smart) the least we can do is reciprocate. Stop and think before you upset the non riding majority of people in your area. You can do more harm than you think. X-C skiers vote and may be members of the town council or own property that sled trails cross.. We wonder why we keep losing trails?.. I was embarrassed to be a sledder today.
