SOUTH SIOUX CITY, Neb. -- Ten cyclists have been biking from California to New York in honor of veterans, firefighters, and police for 9/11.

"I grew up on Bicycles," said Darrell Sales, coordinator.

Sales organized the journey which started on August 1st. Each volunteer came from a public service background.

It was not an easy feat, full of housing problems and flat tires -- at least one flat a day!

"First and foremost, we have a team of different backgrounds so we have to learn our styles," Sales said.

They had held a similar marathon ride on the ten-year anniversary of September 11th. Now, 20 years later, it's just as important.

"Our youth need to understand that freedom is not free," said Debby Gunsolley, South Sioux City Chamberette President, who encourages people to view the memorial wall at South Sioux Freedom Wall or buy a memorial t-shirt.

The bikers aim to arrive in New York City at the Brooklyn Bridge in time for the 20th Anniversary of 9/11
