Preventing teenage pregnancy

I dragged my Mom down to the lake front tonight so that I could use my newly acquired tripod to take some pictures without using the flash on my camera. I'd decided the night before, driving home from the bank, that I would dedicate tonight to camera experimentation and scrubbing old wall paper paste off of the walls in my parents' kitchen. I had wanted to take awesome pictures of dirty factories that blew fire into the sky at night, but taking awesome pictures is easier said than done (sometimes) and I wasn't able to focus as well as I would have liked to. My mom sipped coffee, by my side, and humored me as I took picture after picture of blurry buildings and abandoned benches.
"Why do these cars keep driving by?" she asked me.
"Oh, I am guessing that those are just people looking to park. This is a makeout spot. People come here, up the hill down the road, the park downtown. Pretty much anywhere there is a spot to park and the least bit of seclusion. They probably keep driving away because we're out here in the light, away from the car." I explained.
During our hour long stay, many cars did a tour around the parking lot before leaving. I picked the picture above because you can see a car near the middle on the left hand side and I wanted to tell all of you that the people in that car were having sex. They were there before my mother and I arrived, and stayed (presumably) long after we left. We may not have been able to help those people, but I'd like to think that we prevented a few teenaged pregnancies tonight... Even if, realistically, those kids just went to go park somewhere further down the street.
