The idea is for participants to use the trout as a tool to inject something natural back into a man-made and urbanized space, so that the power of nature and animals can again be a part of the lives of those roaming within the urban landscape.
I was lucky enough to be a recipient of one of these fish and set out to find a good home for him. I don't think there's a more accurate description of 'man-made and urbanized space' than the suburbs. While the 'burbs aren't everyone's cup of tea, I love where I'm living and this particular town embraces nature much more than other areas.
I noticed that my local post box could use a little touch of nature. For selfish reasons I also liked the idea of having him close by so I can check up on him and see people's reactions once he's been spotted. I was also hoping he'd be the good luck charm to forgo a postal strike... but I guess he's not a powerful enough charm.
