We we're driving home at approximately 10 o'clock at night, on highway 92. No one else was on the road and at about 60 MPH something humanoid, grey and tall (but seemed to be hunched) jumped in front of my car. I immediately swerved and turned around to see what it was, that's when we saw something run off into a parking lot, moving at least 25 mph. It was a dark color, it stood on two legs and it was at least 8 ft tall. We rushed to the parking lot it ran into, (this entire ordeal has now been about 45 seconds) and when we got to the parking lot, it had disappeared. This parking lot was big, lit up and not a lot of places to hide. Not to mention that the time it took us to get there was about 10 seconds, far too fast for anything human to run away without us seeing at least something of remnants. We ruled out animals because of the two legs, and again, no human is capable of running at that speed. Not sure what it was, but it seemed to want nothing to do with us.
