Questions about through hike time constraints Me and a good friend have started planning for a through hike during the summer of 2017. He is home schooled, but I go to public school so I have to make it back in time for school to start. The summer will be about 90 days, although I may be able to extend it by a few weeks. We are both experienced hikers, but will 90 days be too much for us to handle? Thanks.
