I did my first parking lot lampost cache a few days ago. I'm afraid that in my attempt to be discreet, I can imagine that I must of looked very suspicious. As I was leaving the spot, a police car pulled in close to where I was. I'm not sure if he was there for me or not, as I didn't stick around to find out, but it did put a little scare into me. Too much stress to be fun for me.
I have to agree with some of the others about finds in playgrounds and school areas too. I'll avoid those unless my kids are with me. And, I think i'm going to avoid the parking lot micros altogether.
