As evening falls, the power in the park shuts off everywhere. The rides no longer work, the lights no longer operate, and whatever was guiding the VIPs has now been deactivated. Earlier than expected, this evening, comes the fireworks display over the lake, but tonight, even though you can make out red and gold, it looks more like a signal flare.
Over the loudspeaker, a voice speaks:
"Attention everyone! Thank you for your participation! We learned a lot of new things. But it looks like it's time to say goodbye, because your ride is here."
In the distance, you can see or hear some form of rescue. A friend coming to help, the police, the military, whoever you would most expect to see coming to help. They're still a ways off, so you have time to say your goodbyes.
You're safe now. That thing still in your head probably won't be a problem, right?
