JMT second try – we have permit for the hike from Mono/Parker Pass trailhead to Whitney Portal starting late July 2021. Still working on alternative entry trailhead: we prefer to  start from Lyell Canyon trailhead and perhaps changing from linear hike to a loop. The trail trace is 310 km, but including side resupply trips we will hike around 350 km. We plan on driving from Chicago. We have a month to enjoy the hike.
Oh, this is very ambitious!
Ale zazdroszczę wam też!
