Food trucks are not the only battle:
“Green carts are a quick and nimble approach that can get fresh food out there relatively quickly,” says Rick Luftglass, executive director of the Laurie M. Tisch Illumination Fund, which has provided $2 million to support green carts in New York. “And because they are mobile, you can follow the need. If sales aren’t good on one block, you can move a few blocks away. It allows the market to build around the customers.”
…Generations of immigrants to New York got their start selling on the street. In the 19th century, the Lower East Side was full of pushcarts hawking pickles, flowers, buttons and hats. But today’s arrivals are limited by strict rules for sidewalk vending. There are multiyear waits to sell those New York hot dogs and a thriving black market for permits.
That is from the excellent Jane Black. Many green carts are starting to take food stamps.
