Organizers for the American International Motorcycle Expo, set for Sept. 23-24 in Columbus, Ohio, will offer free admission to service members and veterans with military identification.

More than 500 exhibitors will be on hand at the Columbus Convention Center, including at least two dozen manufacturers from Harley-Davidson to Suzuki and all points in between. The expo, in its fifth year, had nearly 19,000 attendees in 2016.

All current service members of all branches and components, plus veterans and retirees, are eligible for free entry with any form of military identification, event officials said. They’ll also be asked to bring a copy of this form to ensure free admission.

The event begins Sept. 21, but the first two days are not open to the public. For more on the convention, visit the AIMExpo website or its Facebook page.
