Just a quick thought,
How about a forum very much like the "Meets, Shows & Events" forum with all regions seperated, and have it dedicated to driving experiences in each of the regions. Eg. Perfect driving roads (you know the sort, the one's that only locals know) so if you are planning a trip/roadtrip somewhere you could look it up and read reviews and ratings on the road.
What do you think??
