What about a "where you ride" forum
 

If we made one of these then people could all find some of those hard to find trails and places to ride

I was thinking more like a ride forum, except without the partners where you can post rides.

that would be cool.
but i meant that people could post directoins to sercret trails/spots and maybe a "where its hot to ride in [your state here] for [your bike disiplene here]" forum

This would be useful for roadies too, get some tips on good routes & loops.
