Have you ever driven or walked down a street and read the signs, Some of them will leave you scratching your head. Like when you come to a "T" intersection and there is a stop sigh and a no right or left turn sigh, interesting.
In the open country, or several places I've been where there is a road at the end of a runway, and warning signs can really take you back.
I really would like to meet the person that decided that this sign was necessary, I'm really worried about the people that live in this area really needing this sign.
Now this is one that I'll never understand, really not ever. Need I say any more?
This is a warning, beware of stupid signs, and good luck making the right choice whe you arrive at one.
