We have a few here in MN. Minnetonka Drive In, Wagner's and a few others. When Porky's closed in the mid 2000's, they said part of MN. died that day. Had a lot of good times at old Porky's.
The LH door on our Biscayne came from French lake. I found the same 2dr post car there in 1976, pulled the door off in Feb. that year picked it up and carried it to the front office, that was a workout. Cost $35, I think I got a deal that day.:winner
