Lebanon city officials announced a packed week of events and historical dedications for residents on the week of June 29 as the city marks the 250th anniversary of the nation. On Wednesday, July 1, starting at 8 a.m., city officials will unearth a time capsule at Coleman Memorial Park. Mayor Sherry Capello said that the time capsule was buried in 1976 by the city's bicentennial committee. "After we do a little shovel of dirt, then the highway crew will do the real job," she said.
