In my summer holidays I cycled up Mont Ventoux, just like the two years before. At the summit there was a new sign saying, "Sommet Mont Ventoux 1909m". I was a bit disappointed at having been stolen 2m of my climb, because the sign there the last two summers had said "1911m". A Google image search shows that the sign seems to be exchanged with different altitudes regularly. There are photos on which it says "1910m" and "1912m" as well.
What makes that funny is that the square there is
