Reply To: New Brooklyn Eruv: Time to Accept?

n0mesorah,
“Rav Moshe says that the number would be 4 or 5 times 600,000.
So, at two and a half million it is already problematic.”
Rav Moshe originally thought 600,000 would be sufficient. He then realized that they were nohig to make eruvin in cities containing shishim ribo. He then entertained 4-5 shishim ribo. The last two teshuvos on the matter he stated that the number would be 3 million, and Rav Dovid agreed in Chicago. Rav Moshe’s shita was a work in progress.
