We have it here too ..our signs are in French and Breton ...when ever it's discussed most think it's a waste of money but should be just in Breton.
and a lot don't think Bretagne should be part of France anyway, the guy down at the testing station collers me every year to explain that soon it's going to get independence from France and it was taken illegally etc.
Finally nobody likes a sign more than the French....end of our road makes me laugh out loud when I notice it from time to time.
EDIT: in fact I'm going to count the signs at the end of our road (entrance to village) and nearest guess gets a special prize in the post .
