In 1974, a new apparition began to make its appearance in the streets of Manhattan. Even in that hubbub of crowd and clamor, this strange vehicle attracted attention. It was a standard van of the “U-Haul” or “Ryder” variety. It’s back door was rolled up, showing a cargo of one large wooden table, two wooden benches, and a dozen young men with beards and black hats. From a loudspeaker taped to its roof issued forth a medley of Chassidic songs played on high volume—that is, high enough to make itself heard above the din of a Manhattan street corner. Large posters taped to the sides of the moving van proclaimed: “MITZVAH TANK”, “Teffilin on board” and “Mitzvot On The Spot For People On The Go.”
