Doesn't that thread already exist?
I predict that the most popular start date will be January 1 so people can beat the unbearable heat that begins by May 1 -- thanks to global warming.
It will not matter though because the AT fad will be long over, in favor of the much more popular thru hike of the Syrian Trail that weaves along Syria's log peaceful borders with Turkey and Iraq.
Of course for those who do hike the AT, complimentary champaign will be served by the ATC (which will own and operate Baxter State Park) on top of Katahdin. They even hand out Scott Jurik commemorative glasses to celebrate the 35th anniversary of his still standing FTK.
