This is cruder than anything I've seen in the States, but
it's been long rumoured that people have actually done the same in the forest preserve shitters.
we have the same thing going on here in mexico, it´s the intelligence central that has many spy devices in the ¨hot spots¨ as they call them, funny thing is that many of the hot spots are located in restrooms. bad thing is that i haven´t seen a single photo ´round the web.
i can talk to a snake, but not expect me to hugh it...
