Mountain Grove, Missouri
Back on April 24, 2012, I left Houston, MO, where I'd photographed The Phoenix drive-in theater to head for the next theater on my list, at Seymour, MO. US Route 60 alternated stretches of limited access four-lane with older two-lane highway sections, and on one of these I spotted a derelict drive-in theater screen. The screen was missing half of its panels, but the grounds were well-kept. Inside, I found that a permanent flea market was in operation, owned by Willard and Donna Hill. A building at the back of the field had once been a single screen indoor theater (The Phoenix had a similar arrangement, though on different terrain and with both operations still in business).
The theater was out of business when the Hills bought the property many years ago. They've never operated the theaters but I did get to have good talk with Willard before moving along toward Seymour.
