Kol Nidrei Night With The Brisker Rov
One year after Kol Nidrei the Brisker Rov, Rav Yitzchok Zev Soloveitchick took his son in law Rav Yechiel Michel Feinstein to go for a walk.  Perturbed, Rav Yechiel Michel asked the Brisker as delicately as possible, if this was the time they should be taking a stroll.  The Brisker Rov answered, "I am surprised at you.  If this is not the time to take a walk, then we should never go any day of the year.  This walk however is not for pleasure, it is for my health as instructed by my doctor.  Therefore there is no difference between Yom Kippur or any other day. (As told by Rav Moshe Shmuel Shapira - Uvdos V'Hanhagos L'Bais Brisk)
