I like scouting out free events, so if you’re into visiting museums (like I am), here is one offer not to pass up.

“Smithsonian Magazine Museum Day Live!” is providing free admission for two to participating museums across the United States, Puerto Rico and U.S. territories this Saturday, September 27. This annual event includes a good number of museums and historical or cultural institutions, birthplaces and centers.

The list includes a mixture of places that are either already well-visited, have niche collections or focus on specific subjects. Here is a sampling:

New York City
New York City Fire Museum

Salem, Massachusetts
The House of the Seven Gables

Los Angeles, California
The GRAMMY Museum

San Diego, California
San Diego Air & Space Museum

Washington, D.C.
Newseum

Yet, with all of them, there’s just a slight catch: You must register to obtain a ticket to the venue of your choosing beforehand. Once your ticket is ready, you can download it and print it and/or access it from your smartphone. My suggestion would be to print a copy to take along. Get your ticket here.
