Silent blimp directly above us. No sound or movement or reason. Middle of nowhere. Totally strange.

A moonless night, returning from a fair, maybe state fair, early summer. 
On the way home, we noticed an obvious black hole in the sky. As we peaked over the hilly terrain of the highway, we noticed this "black hole" in the sky. 
As we neared home, we took a side road as a short cut home. We ended up almost directly under the object. It looked like a blimp, except it was not moving and it made no sound. 
As a tough guy, I picked up a rock and threatened to throw it at the object.  
My friend, ((name deleted)), begged me not to and begged me to leave. 
I knew the object was too high to hit with a rock, plus I was also freaked out. 
We got back in my car and went home. That is all.
Witness indicates that the date of the event is approximate.  PD
