I wouldnt start a thru hike anyother way. A very special memory of mine was walking away from the roar of the falls toward the quiet woods, saying bye to dad, and thinking of springer. Theres only two ends to the AT and I like making both special. Not that other ways are not special, but hiking to the top just gives you those feelings that driving up then hiking SB dont. BTW I have done the approach trail 3 times now (only once was thru hike) and its not that hard. Just dont do the steps with fully loaded pack. Start that **** with a bang!
