US rabbinical students bike through America to raise money

Three rabbinical students from America have laid down their gemaras and literally gotten on their bikes to ride clean across the US.
Having started out in Central Park, New York on July 6, David Saul, Zalman Perlman and Shmuel Rothstein rode south, down through the Carolinas and on into Dixie, crossing through Georgia, Alabama, Mississippi and Louisiana.
The three intrepid riders, currently biking through Texas, have undertaken this continental expedition to raise money and awareness for Friendship Circle International, an organization set up by Chabad-Lubavitch to encourage teenage volunteers to spend time with special needs children.
The roving rabbinical students will visit 20 Friendship Circle chapters during their epic 4,000-mile voyage, and are scheduled to complete the ride by August 25 in Agoura Hills, California.
