The Park pass machine almost always sits quietly and does its job! The pass is for entering the park (not for parking in the lot) and you should always carry your pass with you. Pro tip: Buy a 6-month pass! It's more than worth it!
There was that one time when someone thought that using a torch and stealing the pass machine in the middle of the night was a good idea.
It was not a successful caper, but it did mess up the machine.
There was an attempt to fix it on-site. (Did you wonder what the machine's insides look like? There is not a bunch of money in there!)
