Hi, I'm set on hiking the JMT this year from mid July to August but unfortunately missed getting a permit 168 days in advance for Yosemite trail heads (kicking myself hard for that). With the changes this year they seem almost impossible to get now that the 168 day mark is long gone. It has come to my attention that I can get a permit to start south of Whitney on the PCT, for example at Horseshoe Meadows, and go north all the way to Yosemite. The permit won't let me camp by Whitney but I can go up as a day hike and I can end in Happy Isles. This sounds great to me-- I am wondering if there is a catch? It seems like people are reluctant to go northbound for some reason. Is it difficulty? Return transportation problems? (I am coming from NC so this would be important, thinking of flying into Mammoth Lakes.) Please bring anything to my attention that I should be aware of. We're past AT SOBO hikers so we don't mind going against the grain of hiker traffic
