To honor service members, and commemorate the 100th Anniversary of the American Legion, family members of current and past service members, along with the Riverside community, are invited to light biodegradable lanterns and place them into the Des Plaines River at the Swan Pond at dusk. The lanterns will float downstream where they will be retrieved by volunteers. This event, originally scheduled for May 26, has been rescheduled for Friday, June 14 at 8:00 p.m. weather permitting.
