For the past month, I have encountered many north bound hikers on the Trail. Many started the same time I did in Georgia around the first of June.
It was unlikely that they would hit Katahdin before it closed for the winter, but those I met in Maine or eastern NH several weeks earlier had a chance.
You gotta remember my many Zeros where I hung out at Pinkham, or Dartmouth or Sugarloaf so I would have been in Connecticut or New York on this date.
In New York, in June of 1975, I was frequently doing 20 to 25 mile days.
