A nice afternoon visit with Jack Barnett and Dr. Bob Coldren; tasty snacks and an exchange of Christmas presents . . . The Historic Harrisburg Association is holding a "day of service" tomorrow from 10 a.m. to 4 p.m. They are seeking volunteers for odd jobs inside and out at their offices, Verbeke and North Third. The association will provide lunch . . . This is a week of birthdays: Mike Weaver on Tuesday, John Zimmerman on Thursday, Joe Kershner and Bob on Friday . . . At least one local was thrilled that the New York Giants upset the Green Bay Packers and will continue the effort to play in this year's Super Bowl . . .
