Population is down a little so nannies aren't just everywhere like they used to be. Good glass and being able to shoot 500yds + will help a bunch.
Before you shoot make sure it's in a place you can retrieve it.
Glass from the bottom find them before you start up the mountain. Find them the evening before, they don't move much at night.
It's a fun hunt but a lot of the mountain is brutal. You want good leather boots, Leather gloves, walking stick.
