Me and a friend were on our way home from a concert, the females were sleeping in back, we were driving aprox 90 from nashville to lexington, ky. no drugs, no alcohol at concert. we just crossed the kentucky state line when we came across 3 vehicles stopped on sode of road, and above the vehicles aprox 100 feet in front of them, a good 60 feet in the air was a very prominent object hovering, no visible lights, but visible to us, it was transparent, but only enough to make you double take, transparent as casper, in the priginal film. we couldnt hear noise where we were. as we watched this item, for a good minute, we tried to snap a photo, using a note 8 and a iphone and were unable to actually capture anything die to lighting, and being on interstate at 4 am. as we decided we were spooked enough, we decided to continue forward, along with another vehicle that was parked on side. as we approach the object, which hasnt made any movement besides the swaying of hovering, we hesr this loud, harsh humming, and again, we just left a concert, we are deaf temporarily, so this noise had to be loud. it rumbled and just sucked in all. we didnt feel any effects from the encounter, we even stopped a few miles up the road at a gas station to verify what we did see, the other car stopped with us to talk about the experience. we lost site driving away, and never turned around.
