A celebration of culture, learning and the dissemination of knowledge, Smithsonian's Museum Day reflects the spirit of the magazine, and emulates the free-admission policy of the Smithsonian Institution's Washington, D.C.-based properties. Doors will be open free of charge to Smithsonian magazine readers and Smithsonian.com visitors at museums and cultural institutions nationwide.

Last year, upward of 200,000 people attended Museum Day, with all 50 states plus Puerto Rico represented by more than 900 participating museums, including 84 Smithsonian affiliate museums. This year, the magazine expects to attract over 1,000 museums.

"We are proud of our motorcycling heritage, and we're looking forward to sharing the AMA Motorcycle Hall of Fame with Smithsonian magazine readers and Smithsonian.com visitors this Sept. 26," said AMA President and CEO Rob Dingman. "The stories of the amazing people who shaped our sport, pastime and lifestyle are exciting and inspiring. We're confident that everyone who takes advantage of this program and visits the AMA Motorcycle Hall of Fame will agree."

Founded in 1990, the AMA Motorcycle Hall of Fame Museum recognizes individuals who have made significant contributions to motorcycling, including those known for their contributions to road riding, off-road riding and all categories of racing, as well as those who have excelled in government relations, business, history, design and engineering.
