My plan is to do a couple loops of 3-4 days each and at least 1 day hike. I'll be staying in the backcountry campgrounds. I need to find more info on what to expect at those, too.
For example, I assume there's a parking area at the end of the GSMI road where Middle Prong Trail starts. I'd like to leave my car there several days, come back, stock back up on food in the trunk and drive to the next place.
