Sounds ominous...

So, I saw this sign at a local park today, and it caught my attention. True, every park I've ever visited has had some sign near the entrance, notifying visitors that the park is only open during daylight hours.


But I'd never seen this particular turn of a phrase before--the park is closed during hours of darkness. That just sounds spooky. No problem--I'll make sure I'm far away from your park when the Hours of Darkness come. Wouldn't want to take a chance of running into Voldemort...
