Update: Available again. Museum Day Live! is an annual event hosted by Smithsonian magazine in which participating museums across the country open their doors to anyone presenting a Museum Day Ticket for free. This is in following the spirit of Smithsonian Museums, which offer free admission every day.
Registration is now open for Saturday, September 24, 2016. Find participating museums here. Request your ticket here. One ticket per valid email address. Each ticket provides general admission for ticketholder plus one guest. You must pick the specific museum during the ticket request process, and then download a PDF to print out as your ticket.
There are some cool museums around us that now cost $25 for adults and $10 for children, so this can be a significant savings depending on the size of your family. (Two adults can register, and that would allow four total people. Kids can also get their own tickets in case you bring along more people.)
Don’t forget to add the event to your calendar! I’ve probably forgotten about this half the times that I’ve registered.
