I get it, there are some not-so-frum people that go to uman.
Aside from them, why do people go?
Is it because it's easier to daven around people you either don't know or are there for the same reason aka davening well?
I'm not convinced people go for Rabbi Nachman and the kever, if they are, good for them.
Is it the party attitude? some people just like to be around when things are happening?
