You Shall Not Pass! (Photocentric)
Came across this rather sorry looking... fence, if something this small can be considered a fence, while at the beach. Being the geek I am I was immediately reminded of a scene in the Lord of the Rings movie where Gandalf the wizard tells a much larger, stronger, and scarier monster that it can not pass. This "fence" was nothing more than a weak attempt at keeping people off that trail or dune.
