What was likely the first organized motorcycle ride to honor those killed on September 11, 2001 occurred just eight weeks after the attacks. The inaugural America's 9/11 Ride was cold and snowy but weather didn't keep 250 motorcyclists from a rally that started in Washington, DC and ended in New York.

Today, America's 9/11 Ride is a little warmer now that it takes place in August and participation has more than doubled. America's 9/11 Ride commences Friday in Somerset, PA at the site where Flight 93 crashed and caravans to the Pentagon. On Saturday, riders saddle up for the long haul from Virginia to New York City.

"It is our annual ride to all three of the 9/11 crash sites," said Roger Flick, promotions manager for America's 911 Foundation which sponsors the ride. "This ride travels through six states and Washington, DC and is fully police escorted."

Ted and Lisa Sjurseth founded the ride after visiting New York within weeks of the attacks. The couple heard from many store owners that they had no customers. The Sjurseth's wanted to help and as avid motorcyclists they decided to do what motorcyclists do - organize a ride. The ride was later changed to August for the warmer weather and to not interfere with memorials in September.

The 10th anniversary ride welcomed 1,800 motorcyclists who spanned the state of Delaware. When the first bikes were leaving the state those at the end were entering. The entire ride is police escorted usually by 100 police officers from around the country. This year's event is expected to bring about 500 riders.

"We're competing with Harley's anniversary in Milwaukee," Flick said. "With the economy the way it is people can't afford to do both."

America's 9/11 Ride benefits America's 911 Foundation which supports the families of active first responders - fire, police and Emergency Medical Services (EMS). In the last nine years, the foundation has awarded $240,000 in college scholarships for children and provided more than $550,000 to various first responder departments.

The 2013 ride is dedicated to the 417 first responders who died in New York. The ride is limited to 1,000 participants so there is still availability. Online registration is closed but you can register onsite at any starting location or stops along the way. There are various starting locations organized around the East Coast that begin Wednesday and Thursday to get all riders together on Friday in Pennsylvania.

"This is truly a bucket list ride," Flick said. "It is one of the most well organized large rides you will ever be on."
