Fantastic. I'll cross-post this to the MD Creepers board for future reference, they have a thread w/ all the East Coast wheeling spots, maps etc.
The only thing I wonder about is the color/rating scheme relative to other places and the terms used. While Daniel is clearly the most difficult trail out there, and Dutch John has some tough/tight spots, by comoparison to other parks these are not really "black" trails - you can still do them w/ say 33-35s, a locker, and some testicles. At a place like Rausch Creek or Paragon these would be Blues and rated moderate.
All I'm saying is that somebody who dosn't really "know" the general level of the park might see this and expect something different when they show up if they went based solely on that legend. To alot of folks "extremely difficult" means if you don't have 37s+, expect major body damage...
One option would be to change it to "mostdifficult" and "easest" just so that it is clearly relative and not the global "blue-green-black-red" scale used other places.
On another note - why the list of trail names under the red "trail direction" sign? I don't get that.
