i linked this into the description of my Mt Whitney hike video, this is a great detailed explanation of the portal area. //comedy, mountaineers who cant figure out how to get to a trailhead or campground? hehehe... i can sort of see people trying to check in to the campground but pick up a permit at the store? wow. But i'll admit i went to my lower Portal campsite before i figured out the host was at the upper spot... this is very helpful
