Happy Seward's Day, Alaska
While March 27th marks the date of the 1964 Alaska earthquake, today, March 28th, is being celebrated as Seward's Day in Alaska, the day the area now known as Alaska was purchased by the United States. (Technically Alaska was purchased by the U.S. on March 30, 1867, from Russia, but I assume it's celebrated on a Monday to make things easier for everyone, not to mention the whole three-day weekend thing.)
While folks in the Lower 48 are going to work as usual, many places in Alaska are closed for the day. The Anchorage Daily News provides a list of closings in Anchorage, Alaska.
