Checked the main page and the thread and did not see it.
Girls and Boys Town - Posted, No Firearms
At the main entrance, 12 or so feet up on a light pole, right behind the statue of the boy carrying his brother. Its the only sign I have been able to find, and its not all that big. 4"x8", maybe. None of the buildings are posted, so I have to assume that the one sign covers the whole place.
