Ann Mintz is the manager of development and special projects for Philadelphia’s Reading Terminal Market, a winner of Knight Arts Challenge Philadelphia to curate a performing arts series at the popular shopping venue. A white-haired woman watches a group of salsa dancers, moving to the music. One of the dancers approaches her with an outstretched hand. She joins him on a dance floor that has been improvised by clearing a dozen tables and chairs from the middle of a busy public market. At the end of the dance, she smiles at me. “Nothing like this ever happens in North Dakota,” she says. “This will be my favorite memory of Philadelphia.”
