The Ken-Mar Drive-In opened on April 28, 1955, when it was operated by Austin J, Pouliot. The Ken-Mar Drive-In is known to have been open in 1977, but it does not appear on a 1985 topographical map. Most sources list its address as 1631 S. 16th Street in Escanaba, but it was actually in the 7000 block of US-2/US-41/M-35 in nearby Gladstone.
