Blimp shaped craft floating over I805 January 21, 1981 5pm

I was 31 years old at the time , single and working as a technician for At&t.
On January  21, 1981 I was on my way to a wedding in Bonita, California called the Chapel of the Roses.  I was coming from west Chula Vista.  I  came down E St. heading east and got lost.  I grew up there so I was surprised that i was lost.
In those days Bonita still had farmland up in the hills and I  found myself near one and on a dirt road with a great view overlooking  I805 looking west.  It was still light with little  clouds.  I saw the Goodyear Blimp over the freeway which wasn't unusual, although this one had  lights covering the ENTIRE body, not just a screened area.  The lights moved clockwise together vertically, row by row. I was actually enjoying watching it just floating over the freeway very slowly and calmly going in and out of small clouds and not too high. Blimp height, just like a blimp.
While I was watching this and thinking how I hadn't ever seen a blimp like this, it suddenly took off upward sooo fast leaving a trail toward the south.  My hair stood on end.  I realized it was dark now and shook all the way down the hill. I found the Chapel and was still shaking when I told my friends.  No one believed me.
I did report it to a UFO reporting sight where you could call in the sighting.  The guy who took my report said there were no other reports in that area that night.  I no longer remember what reporting entity it was but it was in Washington State.
