The United States Postal Service will not be delivering mail today in observance of Thanksgiving. The Federal holiday also means banks are closed. In addition, all Washington County offices are closed today and Friday for the holiday. The Washington Public Library is also closed for two days, today and Friday, but will reopen for patrons on Saturday. Main Street Washington’s annual lighting ceremony in Central Park will be held tomorrow beginning at 5 p.m., followed by the lighted parade. Join KCII’s Big Red Radio for the holiday festivities in downtown Washington Friday to kick off the Christmas season.
