I saw a vehicle from another planet in May of 1977,

I was driving north to Baker Oregon, left Winnamuccha Nv about ten min. to 8pm. After a 35 to 40 min drive I observed thru my right rear passenger window a Brightly lit cigar shapped object moving along a ridge. It seemed to be pacing my car but stayed slightly behind. I actually thought it was another car on a parralel road up on the ridge. I realized that the object was different and stopped and stepped out of my car along side the road. The object stopped when I did but slowly moved toward a saddle cut in to the ridge. I still thought that it might be a car but was shocked as the object started to move out to the center of the saddle still even with the ridge line. The object stopped in the middle of the saddle for about 7 to 10 sec. The object left in a northerly direction at a very high rate of speed.
Witness indicates that the date of the sighting is approximate.  PD
