Wow, I know it changes a lot year to year but over longer time scale it's even more. Like, there used to be actual dirt interbedded in the rock on Mile. And the drop on the top of Boy Scout is about 2' taller now.Just found this on youtoob (not mine), seemed appropriate. First time I tore a rotator cuff was getting too enthusiastic hitting the step down at 2:45, second time was from loosing traction after landing the drop at 1:24 and burying my shoulder into the side of the trail.
