My first job was picking up at a drive in on the morning after. I was about 14. We'd walk around with cardboard boxes, picking up popcorn boxes, pop cups, bottles etc. We tossed it all onto trach heap and burned it. The further you got to the rear of the theater, the nastier it got, there was articles of feminine hygiene and condoms laying around. I picked those up with a stick, then broke the end off the stick so I would not accidentally grab the wrong end. I got an education in the days when kids were still kids.
The remains of the theater are still there in a used up post industrial neighborhood.
