I never click on the advertisments but this one on my Yahoo mail got my interest.
Nation of Go - BFGoodrich®
Concept is for all car makes on or off road where you can share your best routes.
It appears to be hosted by BFG tires?
Kinda goes against the policy of keeping the best drives secret from public and enforcement.
I searched around the posted routes but was a bit relieved to see my favorites were not posted.
Still it might be a resource if you were looking for a good route outside your local area.
