Smithsonian magazine's Museum Day offers free admission for two to museums across the country, including more than two dozen in North Carolina, this Saturday.
Participating museums include Marbles Kids Museum in Raleigh, Fascinate-U Children's Museum in Fayetteville, Imagination Station Science Museum in Wilson, and Tryon Palace in New Bern (which, by coincidence, I'll be featuring on the site on Friday. I highly recommend a trip here). And there are many more.
You can't just show up at the participating museums to get the free admission. You will need to sign up for the tickets, which will be emailed to you. To learn more and to get your free tickets, go to the Museum Day website.
