My son, 21 year old College Senior and Eagle Scout is considering a similar pace!
He needs a fast paced hike with good support (me) so that he can get to summer school in CT by June, take a month of summer school, and then continue on to Katahdin by 1 Sept. We are arranging good logistics support at all road crossings so he can keep up speed without having to carry more than a day or so of supplies. He will be carrying a ham radio tracker so that we can also map the coverage of the ham radio GPS tracking system called APRS. hence, the good support by other ham operators all along the way.
