Rabbi Moshe Dov Stein Zt’l was one of the foremost experts in Eruvin in our generation. This Shiur was delivered by R’ Stein in 1999. It was given to bring greater awareness to the community about Eruvin. The Shiur was accompanied by a video presentation of the Far Rockaway Lawrence Eruv. The audio portion of the video is on the second CD. Although the Shiur is specifically in regard to the Far Rockaway Lawrence Eruv, it is applicable to all Eruvin in metropolitan areas.
