Springfield’s Historic Cannon Ball House, located at 126 Morris Ave., will be open on Sunday, February 18th from two to four. In honor of it being Presidents’ Day weekend, two samples of presidential penmanship will be displayed. One is a letter that George Washington wrote from Springfield during the Revolutionary War, while the other is a piece of correspondence from Herbert Hoover. These letters are only displayed once a year; so do not miss the opportunity to see them at the Historic Cannon Ball House. Hours: Sunday, February 18th from 2 to 4.
