The Skyline Drive-In opened before 1950.  After 1955 it may have been renamed Rich Drive-In, which open from before 1961 to after 1975.1  

The Rich Drive-In was owned by Van Anderson and was located by the mountains on the west side of town.  The Rich Drive-In was later demolished and I-70 now occupies part of its site.
