>>457317Mount Katahdin in Baxter State Park. (The northern most point of the trail.). It is an "average" time of year when they close the mountain for the season. After this, it is too much trouble to go fetch peoples bodies off the mountain in the snow.
You need to keep track of the date and try to get there by the end of September. Or you'll have to wait until the following year to finish.
A friend of mine didn't make it in time in 2013. She had to go back up there in 2014.
