Hard to say, who has ridden all the trails on all the islands?
The C grade was for the whole state and the reason was lack of organization.
As you know we are trying to get "organized", just not in the way IMBA wants.
Which do you think is a better and more efficient way to manage trails?
A. Organize and work with the local land mangers, i.e. go official, and waste a lot of time that could be spent actually working on something worthwhile. Maybe even pay to access private lands.
B. Build wherever, whenever, whatever we want and hope nobody notices.
I pick B. thats one of things I like about mountain biking, no rules, creativity, adventure, hiding from the "law", you get the idea.
