A chassidish American lady once told me that a lot of chassidim come to EY for Lag B’Omer to go to Meron. Apparently, it’s considered a “big deal” by the Chassidim.
As for me, I’m with WTP – I can’t handle crowds. It is probably an amazing uplifting experience – but it wouldn’t be for me. I’ll find another opportunity to go to Meron be”H.
