The Sporting District was an area near 16th and Harney Streets in Omaha, Nebraska where city boss Tom Dennison kept the majority of his gambling, drinking and prostitution interests from the late 19th century until the end of his reign in 1933. "Cowboy" James Dahlman was reputedly voted to the first of eight terms as mayor of Omaha because he was more tolerant of the Dennison's "Sporting District" in the middle of the city.
