Mark your calendars now and plan to join us for a fun, festive and free day celebrating America at 250 this July 4 between 11-4. Dust off your favorite cookbook and bring a dish to share at "America's Potluck" at the Polson. Admission is free all day, the Daughters of the American Revolution will be doing first lady skits and Museum Director John Larson will present a gallery talk on the museum's "Moments that Made Us" exhibit which debuts that day.
