Out on one of my geocaching hunts, I past this gateway before going into the countryside. When I looked at all the warning signs I thought, yes we get the message that it might be a little dangerous inside, they even put yellow and white tape on the entry post.
Now I can assure you that all these warning signs would not be the main reason to deter you from entering. In fact I just wish this computer could give you smelly vision because this is actually the local sewage works. There would be only one person that would want to go through the gate and that is "Winnie the Pooh".
What fun - very well spotted and captured. I particularly like the Thieves Beware sign. Not the first place I would think of to break in and steal something!
