(CNN) Thousands of motorcyclists rode across New Hampshire on Saturday to honor seven bikers killed in a collision with a pickup truck in June.

New Hampshire State Police said more than 3,000 people participated in the "Ride for the Fallen 7," a 90-mile journey to the site of the crash.

The cyclists started their ride at noon, leaving from a biker bar in Laconia, and traveled north to end up at Route 2 in Randolph near the motel where the victims stayed before the accident. State police escorted the group for the length of the route.

"It's an unprecedented accident, so we might as well have an unprecedented memorial," organizer Steven Allison told CNN affiliate WMUR
