From ski lift and grooming operations I guess…
Particulates settles in valleys, depressions, pockets between mountains…
As for snowmobiles… just as bad but disapaiates quicker into air…
Other than that… rush from fresh air is just as good as… getting it on…
Must be a serious POST CO-VID effect being around it constantly in crowded areas…
Difference is astounding
