The “Datche” vacations that many gedolai yisroel took in the summer consisted , for the most part, of them learning in forested areas and taking walks while speaking in learning with other Talmidei Chachomim .
Many of the beautiful pictures of Rav Baruch Ber speaking in learning with other Gedolai Roshei Yeahivos and also various Admorim are from those “vacations”.
