Only in Ireland

I love these sorts of signs - If you are driving on the left you can do 80km/h but if you are driving on the right you can only do 50km/h (also, I wouldnt fancy doing 80kms down that lane!) . I've come to the conclusion that the leprechauns go out at night and change them. For 2 years the direction sign for our village pointed the wrong way at a crossroads I did try to change it once but it was rusted in place. Mysteriously it was corrected soon after!
