This sign alone is one thing. But if you pair it with the yellow sign on the other side of the road, it takes on another dimension. :)
Click on the picture for a bigger shot so you can see the yellow sign.
Updated January 8: Sorry, it pointed to my Flickr and if you don't have an account or are not logged in, you do not get the option to view "All Sizes." Try to click on this link for the big picture. If it's still not big enough, use the resizing button that will appear on the image if you roll your mouse over it. Hope it works for you. Let me know if it does not.
