I agree, don’t worry about it now. On my first hike, we hitched from Katahdin to Millenocket for the night, then down to Bangor or August, where we were picked up by the parents of my partner, who drove me to my grandmother’s house in Massachusetts. On the second hike I got a ride from a fellow hiker to a town in Massachusetts where I could get a train west. Usually there will be other hikers finishing the same day you do, and at least one is likely to have transportation out - at least as far as the nearest bus station, and maybe all the way home.
Funny story - on my first AT hike, one of the hikers decided to quit at Troutdale. (He missed his girlfriend.) He had no idea how to get home from there. We stopped at Country Cookin’ for lunch and left our packs outside (not recommended). A passing car saw the packs and decided to come in to meet us, since he had hiked the AT the year before. Turned out he was heading for the same area that my friend lived in, about 300 miles away. A ride was offered and accepted. Now that’s trail magic.
