Here's a photo scanned from my copy of the Black River Historical Society's Images of America book on Lorain. It's a nice photo of the Lorain Drive-in from 1955. (Click on it for a closer look.) As you can see, the area was still mainly farmland, at least on the south side of US 6.
And here's a Google Earth screen shot of the Hold It Self Storage property today along with the real estate shown in the 1955 photo (roughly).
It's interesting just how much development has sprung up in the last fifty-five years. The lake side hasn't changed too much in that area, but the south side has exploded with apartment complexes, such as the West Lake Apartments (immediately east of the drive-in in the photo) and residences.
