I was at the Kever yesterday @11.30AM on the very 1st Johrzeit. A lot of people there. I went before the big gathering @2.30PM which would have been far too crowded. …. I also paid 20 Shekel to have 1 “Ous” in a Sefer Toroh they were finishing in his memory.
I have met the Rov many times, in USA, UK & Israel.
