So I've been driving aroung Mosquito Lake Road trying to find the access road to the twins (Blue mtn. rd.?) I think I figured out which road it was, but there was a an open gate with a posted sign by the Cambell group :No motorized vehicles beyond this point/ gate may be closed and locked at any time." So who is the cambell group, and how do I access the North Twin. Do I have to start hiking from Mosquito Lake Road? Beta Please!
