Was looking for a cache, but had decided the six inches of water was just too much for me to worry with wading through. As I was returning to my car, a police officer pulled up and asked if I was okay. Explained what I was doing there and he looked at me like I was crazy and said, "Umm, okay."
I also had to deal with a security guard at a community college. I saw him and told him what I was doing and even told him who had hidden the cache. The guard laughed and said, "She's always doing something crazy like that."
