My family was searching for a cache outside of a museum on a university campus. Our son was inside, performing in the band at a function, and we were caching to pass the time while waiting for him. A campus security officer stopped his truck and got out, walking over to us. We were ready to explain that we were just goofing around while waiting for our son, but we didn't need to. He called to us, "Did you find it???" Turns out, he'd looked for the cache several times and never located it. He searched with us for a while, but we never found it. The cache was later disabled.
I think it's a pretty cool thing for a security guard to do, cache on the campus! Gets him out and about and seeing the world he's patrolling.
