Tucked down a side street off a long commercial strip on the eastern side of Christiansburg is this drive-in theater, a rare survivor of a once-common type. A bright-red neon star on the back of the tall movie screen structure summons movie patrons. The drive-in's speakers, ready to hang on car windows, are set in curved rows on terraced grassy slopes that step down to face the big screen. Nearby is another mid-twentieth-century survivor, Dude's Curbside Drive-In (1505 Roanoke Street), where carhops serve patrons who make their selections, including a Dudeburger, from a big menu posted on the gabled front of Dude's small building.
