R. Moshe Feinstein on the Flatbush Eruv (15 Shevat)

שו"ת אגרות משה אורח חיים ד:פז 15 Shevat 5738 (1978)

Could the rabbis of Flatbush construct an halachically valid eruv? R. Moshe Feinstein is pulled into that conversation because he had been referred to as the rabbi certifying the validity of the eruv. His view pushes the comparison between our cities today and the camp of the Jewish people in the desert much further than his predecessors had done.
