That redoubtable Orthodox blogger, Honestly Frum, has this tale from Jerusalem. It begins:
“Last year the Satmar Rebbe visited Yerushalayim for the opening of the new Satmar Yeshiva. Due to the fact that men and women were standing on the same side of the street the procession was delayed until they separated, and there was a mechitza setup on the street to facilitate the separation. In Ramat Bet Shemesh there are areas where they already have separate street sides. (I wonder what took so long). On Friday the megaphone (the “vehaya machanecha kadosh”) people went around announcing men and women should walk on opposite sides of the road during the weekend.”
