comments: Jim, you have a page for a UA Marina Auto Movie in Monterey Park, California. Monterey Park is an inland city east of Los Angeles, and only ever had one drive-in, that being the Floral. The UA Marina Auto Movie, given its nautical name, must have been in Monterey, California, a coastal city in the northern part of the state.
The topo map showing the supposed location of this drive-in actually shows the location of the Edwards San Gabriel Drive-In, in San Gabriel, California, a short distance northeast of Monterey Park. I grew up in the neighborhood and remember it well. I\‘m not familiar with the city of Monterey, so I can\‘t help you to find the actual location of the UA Auto Movies. Drive-Ins.com says it was on 8th Street in Monterey, but has no exact address for it. -JV
