Along the same lines.
When they built INALA in Bris they went in circles and left the centre part bush.
Needless to say all the local kids learn,t to ride there.
Next thing the signs went up " No Vehicles ".
Mate of mine lived there and used to pinch the signs and hide them.
Then the RSL , or whatever, was built and a huge carpark was put in the very spot where the signs were.
Now the powers to be had to pull the " No Vehicles " signs ,which were magically reappearing , DOWN.
My mate had kept the lot and was putting them back UP in the same spot.
Every one used to stand and watch them pull them down.
