Ranch subdivision built on a former WWII-era airstrip north of Casper

Bar Nunn is a 3,000-resident town north of Casper built on the site of Wardwell Field, Natrona County's original municipal airport. Rancher Romie Nunn purchased the 640-acre former airfield in 1954 for $20,500 and subdivided it in 1958, turning runways into streets and laying out homes along them. The result is a distinctive elongated street grid still visible from the air. The town incorporated in 1980 and has grown 35% since 2010, with some of the newest housing stock in the state. It carries a notably high homeownership rate (95.8%) and the highest median household income (~$99K) among Casper's three suburbs. A new municipal police department launched in 2025, with full operations expected by mid-2026.
