Just for the heck of it, here's a question for thru and section hikers: How many additional did you end up hiking that don't count toward miles on the AT? I'm thinking of mileage like the approach trail in Springer, the many .6 extra miles to a shelter, miles to towns, out and back on Katahdin and all those scenic overviews. My guess is most 2000 milers are more like 2500 milers. Section hikers, please feel free to chime in.
