Admission to the Juliette Gordon Low Birthplace - a National Historic Landmark and popular house museum that's a must-see for Girl Scouts - will be free on Saturday to visitors who download a ticket from Smithsonian.com.

The opportunity is part of Smithsonian Magazine's Sixth Annual Museum Day, a nationwide initiative that includes venues in all 50 states, the District of Columbia and Puerto Rico.

"We're excited to be part of a program that couples our name with the Smithsonian," said Katherine Keena, program manager for the Birthplace.
