I was riding my moped on a dark gravel road back home with my buddy and as I make a left turn, I can see in my headlights someone doing jumping jacks on the middle of the road ahead. I pull aside thinking what the hell did I just see as my friend who was following me pulls next to me, lifts up his visor and is like ‘did you fucking see that?!’ We immediately go back to inspect and there’s no sign of anyone anywhere.
