This Saturday, September 25th, is one of my favorite days of the year- Smithsonian's Free Museum Day! If you go to this site and print out a coupon, you get free admission to any of the participating museums. We've gone every year for the last 4 years and have had a great time checking out lots of local museums. This year we're off to Seattle's Museum of Flight again. Check the site to see participating museums near you.
