It is a little annoying. On the flip side if they didn't do it, you'd have all sorts of commercial operations out there crowding up your areas, taking parking, and the like to make a buck. Squeezing the recreationalist out due to crowds. It's a tough one to manage for sure, and there are repercussions, such as your small operation.
The weekend that we run our on snow definitely has an effect for other people who are out there to do their own thing. If week after week I showed up to that, I'd be pissed and would be emailing the Forest Service to do something about it. Just to play devil's advocate here.
