The National D-Day memorial in Bedford is preparing for up to 10,000 visitors for a weekend of events marking the 70th anniversary of the Normandy invasion. Organizers have been coordinating plans with veterans groups and nonprofits across the country; and are expecting about 300 D-Day veterans and nearly 1,000 WWII veterans attending today’s ceremony. The anniversary will be marked in a ceremony, where “Homage,” a sculpture honoring the Bedford Boys, will be dedicated. A P-51 and a C-47 will fly over, and there will be a parachute jump by the Golden Knights. Tomorrow, a 1940s-period parade featuring vintage WWII vehicles and themed floats will take place in downtown Bedford. A bell will toll at 11 a.m. in recognition of the 19 Bedford residents killed during the Normandy invasion. More information, including parking details, can be found at www.dday.org.
