CSINo not Crime Scene investigation - Child Scene Investigation.
Part of our fall colours hunt last week included a walk along the Goderich waterfront. As we covered the boardwalk we went by a bench with some forensic evidence on it. The evidence, below, suggests strongly thet there is a nearby children's playground, in an environment conducive to bare-footing, like a sandbox. And in fact this bench was directly opposite a children's playground, based in a large sandbox.
As we walked back the other way, we found the dinosaur had joined the shoe-owners in the sandbox.
