First, are not Black diamond trails optional?? Should they not stay BD if they are!!!
If people cannot ride them then stay off.
Second, I thought that the new trail being built off of roller coaster was to be a BD trail??? It looks like the second coming of the ridgeline. ( the ridgeline is a wonderful trail but is it a true BD trail???) The less you do to a BD trail the better, keep it natural. (keep the roots, rock and everything else, don't cut them out! Example Carter road!!!)
Come on people lets keep the optional just that NOT EVERYONE HAS TO RIDE THEM.
