I致e been carrying my little tube of sunscreen for a long time now. I was happy I had it when I spent all day above treeline in the Whites (presidential section) and for Katahdin (not that I had to use it since a rainstorm hit right after I reached the sign) and for the Roan highlands. I知 now in Erwin, TN and heading south. Since I知 picking up my heavier winter gear for the Smokies I知 thinking about taking out a few items to save weight. Any sections south of Erwin, TN that are exposed for a long time? Thanks in advance!
