Similarly, I see lots and lots of orthodox Jews when hiking in New Hampshire.
I don’t know. Just one of those things groups of people like to do. They probably also like seeing others from their community while on vacation so they encourage others in their community to go as well. And then it just takes off as a common recommended vacation spot amongst themselves or something.
Also I’m sure it helps that people from those communities report that they had a good time, they were safe, and weren’t harassed or anything.
(I have no idea if that’s accurate, but that’s my guess)
