Australia has what appears to be a government owned webpage dedicated to mapping out all the public toilets in the country. There's even a My Toilet log in. This might just be the finest use of public servants and tax money that I've ever seen, even if it is kind of useless to a person without web access and in desperate need of the dunny. Still, in those cases, trees, alleys and trucks are fair game. I wonder if they're listed?
