Aside from being a fascinating site with many interesting pictures and stories, Smithsonianmag.com, has sponsored the annual Museum Day Live for more than a decade.
Long story short, this is a day during which you may obtain a pass which will allow two people to attend a museum affiliated with this special day for free. In Memphis there are three museums associated with the day. One is the Dixon Gallery and Gardens. The other two I will let you find out for yourself using the site’s Find a Museum page that lists nearly 900 participating museums spanning all 50 states.
