Back in my day (78-84) I never heard of missing strollers or anyone ever taking anything from a stroller. There were a lot of people who, running to catch the next ride at the diving bell, would grab their kid, abandon their stroller, and say, "Junior, we'll be back shortly, can you watch this stroller for us?" Of course, all of us replied "yes!" then soon as they rounded the corner, we forgot about it. It really was a non-issue. Too bad things aren't like that everywhere today!
