very strange ground activity. possibly military. a very large amount of activity going on in total darkness.

While driving from Las Vegas on this night, I had pulled over off of I-70, onto a ranch exit approximately 20 miles west of Crescent Junction (turnoff to Moab) I had done so because I was very tired, right before I had pulled off at this exit, I had passed a white 5ton commercial style panel van with no markings whatsoever, not even a U.S. DOT number. I went up the exit ramp, and the van that I had just passed had shut its lights down to a military style blackout drive. (very dim marker lights) I had stopped on the entrance side of the turnoff ramp to catch some sleep. upon stopping, I noticed that this same van had turned off to the right at the top of the exit. I tried for an hour to get some sleep at this location. but I found it was quite impossible.  a train had passed by on the railroad tracks adjacent and to the north of the highway exit. it had stopped as well, and dropped off two railcars at this location. after witnessing two more vans exiting the highway there in blackout drive, and hearing the sounds of alot of heavy, slow moving vehicles in the distance, without a hint of bright light anywhere, I was sufficiently scared enough to leave the area.  about a month later, I had read the PM article on area 51, and its closure ant move elsewhere, after looking at a flight map for the western portion of the US. I also discovered that this area was restricted airspace, with no air bases marked in the area
