Jacob Soboroff just got a new HD video camera and went over to the Cornfield state park downtown yesterday to try it out. Walking the grounds he saw Huell Howser, "my idol in all things television," filming a segment for KCET. Jacob headed over, camera running. At first Huell looked rather disconcerted at the interruption, but pretty soon life was imitating art — or something like that. They interviewed each other and talked about the park, while Huell's guest cooled his heels in the background. Score it advantage Soboroff. His piece is up on YouTube while Huell's will air in the future on his downtown series.
