Why haven't east coast mtns made little zones in their treed areas or on the side of their steeper but featureless runs, that have little 10-15 footers with good steep landings. Seems like it would make many of the mountains on the EC a bit more fun.
Heck why don't western mountains do it too? throw the little "cliff" signs at the top of the run and also to mark the feature and that should take care of the liability aspect, no?
It'd be pretty easy to make it look natural too. Just install a retaining wall with a concrete facing made to look like rock.
