I love going to museums, especially science and natural history museums, but at $10 to $12 per visit, and hours that never coincide when I'm not working, it's not a joy I easily experience.
But Saturday, Sept. 27th, Smithsonian Magazine is sponsoring Free Museum Day around the US!
The site has all the information about participating museums. I may take a trek to the Peggy Notebaert Nature Museum which, along with having a very difficult name, has an awesome butterfly enclosure where I could literally spend hours.
Have fun and let me know where you go!
