Tim Hunt, associate publisher and long time columnist at the Pleasanton Tri-Valley Herald, is leaving the MediaNews-owned newspaper after a 37-year career that dates back to when Floyd Sparks owned the paper. “I’ve just decided now is a good time to move into a new chapter in my life,” Hunt, 56, said in a story printed this morning in the Tri-Valley Herald. “I’m really excited to find out what that next chapter will be.” The story included comments such as this one by David Rice of the Tri-Valley Community Foundation: “Tim is like the eyes of the community. He’s not only someone people know, but many have seen him grow up here and take a leadership position in the community.”
