Fresno Ca, strange ufo trail in sky.

Fresno Ca, strange ufo trail in sky. Dec 19 2018
Me and son were hanging out in my backyard we saw a strange swirl in the sky over the 99 by clinton. Not sure what to think about this. I always see strange things in the sky over in this area by weber clinton turnout. #Fresno Ca, #ufo, #aliens, #area51, #strange, #ufo trail in sky, #epic,
