Did anyone see the lunatic in boro park? He was driving a geen honda civic with edited plates. He tried bargaining in the edited store, and stole his own car from the valet parking at the other edited store. He cut off the other lunatic who cut everyone else off on 14tg avenue. And he swerved down 39th with sufguniyoiys clutched in both hands dripping jelly on his green civic. He will reportedly be davening at emunas yisroel tonight, because he’s a moony.
He should be considered armed with deep dish pizza and dangerous. If spotted, you should hide syags family and call shomrim postehaste
So bottom line you can’t use pi tikrah as a mechitza for an eruv for the outside, since we pasken like rava and the lishna kama–yes? But see rav weissmandel re eruv in williamsburg, and rav moshe.
