Not really. The pic I showed isn't as difficult as the pic Troie picked. Not difficult to seperate at all.

But yes, one issue I find is people coming out here, experienced in technical trails, then find they are in over their head. Their black diamond is closer to what I consider a blue for example. Especially if they hit the shore, lots of people get smoked by the 'easy' trails on fromme.

The real difficulty would be in creating a national standard. Some people would likely be heavily offended if one was ever implemented.
