Obedezca Señales! Dept
I don't know whether you can tell from the picture, but the sign says, "Gates must remain closed."
(The title of the post comes from the road signs one sees at regular intervals when driving through Mexico, commanding you to "Obey the signs!" I've always found that intrinsically amusing...though not quite as surrealistically pointless as the sign that used to sit out in the middle of a field in England, which sign read, "Do not throw stones at this sign!")
