In two vocations, insurance and retail, we often referred to an 80/20 rule. 80% of your problems would be caused by 20% of you customers.
As I observe things going on through the snowmobile threads here, and my own observations on my own property's trail and neighboring areas, I have to think that a similar ratio applies here in snowmobiling (and probably boating). It would seem that a relatively small percentage of operators are responsible for most of the problems in our use of resources.
Sad state of affairs that a few can cause so many problems for so many.
