Sometimes, searching for things can be fun. The increasing popularity of scavenger hunts, geocaching, and escape-the-room games attest to that. When I was a kid, though, we didn’t have quite as many of these opportunities, and I wasn’t one to get out very often anyway, so most of my recreational searching was done between the pages of a book. And of course, in the early ‘90s, there was no search-puzzle book greater than Where’s Waldo.
