"I heard on the radio the other day he (Dennis Richmond) is set to call it quits some time in 2008."
He's certainly entitled to retire. According to the KTVU website, he has been anchoring the 10:00 News since 1976. Co-anchors along the way were Barbara Simpson (more recently, the right-wing talk host who bills herself as "The Babe in the Bunker"), then Elaine Corral, Leslie Griffith, and now Julie Haener.
If he retires in 08, that will make 32 years - probably a Bay Area record. Dave McElhatton was anchor on KPIX from about 1977 to '98...about 31 years. As far as I know, nobody else even comes close.
