The Patterson, located on VA Rt. West 6, opened in 1966 in Richmond, VA and was a state-of-the-art drive in at that time. The problem, it turned out, they built it on swampy land. Oops. In the early 70’s, the area suffered major flooding and added to the water problem. I understand the mosquitoes would drive you nuts while trying to watch a movie. The Patterson finally shut down in 1981.
