Trail

I saw this weird pattern the other night on the concrete around the fountain in Dowanhill Park. But as is typical, I didn't have the phone battery to photograph it then.

So here it is in sunlight. I have no idea what made it. It looks like some creature's trail, but I don't understand how it could be. Maybe some kid was just playing with a toy there while the concrete was setting.

I feel like a clueless dork.
