This was how many immigrants were fed and employed when they entered the United States at the turn of the 20th century. My grandfather was a rag peddler with a horse drawn cart. My uncle was a deli man after working a cart on Maxwell Street. Carts were the road food on the streets of New York and in Chicago (Maxwell Street) and remain in NYC. Gotta go. I’m training six students for the October Hot Dog University program this week end.
