I think the fair analogy is that of a small town. I'm not from one but have met enough folks and passed though enough of them that I get the gist of it. Perhaps small towners would have more to add.
2200 miles by 200 feet wide makes it a small town. When you hike the AT probably best if you remind yourself of that and a few small townisms.
Everybody knows everyone else, and for the most part knows everyone's buisiness. While a bit less so for those outside the bubble, I pretty well knew everyone or heard of them when I went SOBO. If you want to lay low, it's possible to stay on the outskirts of town. Stay out of the newspaper (journals) and lay low at shelters or hostels.
Eligible single ladies are always the talk of the town, no less so on the AT.
When something bad happens, everyone pulls together and helps out.
When you do something bad, everyone pulls together and reminds you of it.
If you do something really bad, probably best to leave town.
It's easy to get a reputation, and hard to shake it if you don't like it.
One night stands are impossible in a small town, that's why you go to the next town over.
In a small town people don't hold a grudge, they recruit friends, family, and neighbors and start a fued.
Men gossip worse than the women.
But all that said, it's a fine place to live, you just need to follow the rules. The unique thing about the AT is the community, but don't forget that community exists or that just because you sleep in a different place every night you can move out.
