Yesterday, I encountered a few vehicles that were parked at the gate, despite the plain signage that says that it is not legal to park there. For example, there was this SUV that was parked right in front of the "No parking" sign (just in case you had a difficult time to recognize the sign, what with all the colorful foliage, I've highlighted the sign):
What's more, I decided to look up how many of the previous caretakers kvetched about no parking.
In 2007, in 1991, in 1989 (twice), and in 1987 In other words, it's been a consistent problem.
And I'm sure that the previous caretakers didn't note every single instance of having to report a vehicle (and not every caretaker wrote in the log book, either). I think that the number of people parking at the gate has diminished, but it is still higher than what would be the case if people followed the law.
