Why would Hershey CEO David J. West, 48, leave his high-profile, high-perk -- all the Reese's Minis you can eat! -- position to head up a smaller company, Del Monte Foods, that produces things like Contadina tomato paste and Milk Bone dog biscuits?

Plus, his daughter's going to college In California, and Del Monte is based in San Francisco.
