Former Maine resident Bob the lobster shows his stuff prior to his release into Boston Harbor this week. The 10-pound decapod had been cooped up in a Littleton, Colo., restaurant for a couple of months when he was raffled off at a charity function. Now Denver television stations and the restaurant’s owners are fielding calls complaining about the way Bob was released. Seems he lost a claw in transport, and a band was left on the remaining one. And oh, Boston Harbor’s rife with lobster traps.
