Did you ever play detective as a kid? I grew up playing/watching Where in the World is Carmen Sandiego and reading Nancy Drew and Encyclopedia Brown books, which admittedly were a bit before my time, but were some of the best reading material around, in my opinion. Doesn't everyone fancy themselves a gumshoe?
Once upon a time, my dad and I played actual detectives. I was probably 11 or so at the time, and we were out walking during the winter and somehow found a Wisconsin Heights High School class ring near our house in a snowbank.
