I once lobbied for blue squirrels as trail/path markers. Just tie them to a tree or something with some slack so they have some freedom...and put them in pairs, so they can talk to each other about the local sports team, the economy and other squirrel-related topics.
I was voted out. The city decided to use "safety orange" manatees instead. They don't have as strong a union as the squirrels do...
And where can I buy an "asshat?" Do they wear them on the Tour?
