The exchange reported by Rabbi Zajac

Rabbi Zajac relates that Rabbi Stern told the Rebbe he had made an eruv in Miami. The Rebbe's response was to ask whether Miami had shishim ribo.

The question goes to the possible status of Miami as a reshus harabim. It treats the population and public use of the city as a condition to be investigated before the constructed route can be accepted.

A Rav who had established a city eruv

Rabbi Stern was not asking an abstract question. According to the account, he was reporting an eruv he had actually made in a major American city.

The Rebbe's immediate focus on shishim ribo places the large-city facts before the details of the boundary and shows that those facts could not be assumed away.
