Rav Hutner as a young man studied in the Chevron Yeshiva which was located in ... Chevron [after the riot in 1929 they moved and today the yeshiva is in Givat Mordechai in Yerushalayim]. On his way home he stopped in Dvinsk to meet the Rogochover. He said that he was coming from Chevron. That was alllllll the Rogochover needed. He immediately launched into an complex pilpul about the status of Chevron as an Ir Miklat and the Bavli's, Yerushalmi's and Rambam's were flyin'. Only a genius like Rav Hutner could "hold kup" and follow the flood of information that was being presented at rapid fire speed.
The Rogochover was koooooolooo Torah!
