As many others have mentioned, you'll be in a good area to hitch if you need to. Hopefully you won't have a problem getting a ride. That being said, before we became hikers, I would never have picked up someone hitching along the road. However, since we've become hikers and especially since we hiked on the AT in 2005, we have always picked up hikers who are hitching. This does not mean we will pick up
anyone who is hitching, but if someone is along a road we know is around hiking trails (ie. along Rt. 16 or outside of Gorham on Rt. 2, in Grafton Notch, etc) and they have a pack and look sort of dirty and stinky and tired, we'll stop to pick them up if we have room. We figure it's good karma!
Plus, we've been in the situation where we've had to bail out of a planned car-to-car hike due to illness, and someone was kind enough to pick us up, so we know what it's like. Of course, we told this guy we might smell and perhaps we'd be better off in the back of his pick-up, but he said, no come in on. Then, about 2 minutes later, he rolled down all the windows and said, yeah, you guys DO smell
