An interesting combination of signage, but the lack of detail in the trees (a windy day?) combined with what looks like over-sharpening of the grass lets the photo down for me. I am interested in knowing what it is that is in half a mile, though!
Funny joke. :) The trees and plants look a bit weird, though -- maybe oversharp? And I've never seen a sign look like that, feels a bit odd. So 5 from me.
