I was driving on the freeway. maybe the 91 on dec 24 evening or 101 on dec 23 evening. it fell right in front of me. my initial thought was it was firework except the sky was clear and it was the only firework if that is true and it stayed bright for a little too long to be firework. it streak across the sky and even at the very end of it it was too bright and remain the size of a softball before it just disappeared.
