I was driving home from the town of Lake Elsinore. Turned up Country Club Drive from Lakeshore Drive toward Eastern Hills. We have a lot of air traffic here because of near-by airport/sky-diving, hang-gliding, balloonists, private planes, military planes and copters etc., activities so, I'm very aware of what's in our sky.

Looked up and noticed bright silvery, shiny oval quite a distance up and high in sky. I slowed down and stopped to have a better look because object was not typically shaped. No wings, no tail, no sound. Was not the usual "sky stuff" we see here.

Watched object for a few seconds as it sharply bobbed up and down while steadily moving toward the south-east. I turned away briefly, looked back and it had completely disappeared. Eastern sky view is open to view planes for a long way out but there was no hint of the silver object.

I continued on toward my home thinking.. "I believe I just saw a UFO". Parked car approximately one minute later. Went out back to search sky some more for object. Found nothing as I viewed the entire eastern sky. Object had been traveling silently toward the south-east. Almost looked like who ever was piloting the object was moving it up and down as they flew along. What I mean is, a plane just moves along in a straight line. This object sort of "played" as it flew.
