Come to Lakewood if you want to see what so-called Ultra-Orthodox (more accurately known as: Yeshivish, Chareidi, or Frum) people are about, and if you want to meet super-nice people! I could write a book about how nice people in Lakewood have been to me every time I’ve been there.
From strangers (or near-strangers) opening up their homes and letting me (and others) stay by them and not making me feel the least bit like an imposition to strangers (or near-strangers) offering me rides, people I barely know giving me gourmet meals when I happened to stop by their house unexpectedly, a community of people who are always super-nice and sweet and friendly. People who are always ready to help with anything and always have a pleasant word for whomever they come into contact with.
Note: This is not to take away in any way from the above-mentioned places. I just happen to know about Lakewood, and not about the other places.
