Nothing major comes to mind, but I may as well put my two cents.
There's this old burnt down garage on the side of town a few minutes away from my house. Inside this collapsed garage is a pick-up truck, and outside is this faded sky blue low rider car (I don't care about vehicles so I haven't the faintest on its actual model).
This car clearly hasn't been driven for a LONG time considering its wheels have completely melded with the asphalt.
Yet oddly enough even in the middle of winter, this car's paint still looks somewhat pristine. As if someone doesn't care enough for the car to fix it, but regularly cleans the car. Granted the car still has a SMALL amount of rust around its edges, but for something with completely brown, melted wheels, its body barely looks aged. I have never seen anyone walk near the car, but someone MUST be taking care of it.
On a less interesting note:
My college has a big bell that rings with the turn of each hour. Nothing out of the ordinary.
Suddenly since the start of this year, every day at 12 o' clock noon, it starts playing this weird tune instead of its usual bell-ringing. Since the area around campus is open, there is quite the echo. This echo makes it both creepier and made it harder to find where it was coming from. Originally I though it was just some strange food truck or event playing far away.
The melody itself is a bit haunting. Sounds vaguely like a wedding song yet without soul. No one talks about it, we all just go about our day as normal. Why the clock tower now does this still has not been explained.
