A century ago, when most roads in the United States weren't paved, two intrepid sisters from Brooklyn embarked on a remarkable journey — a 4,000-mile trek across the country aboard motorcycles.

Augusta and Adeline Van Buren wanted to prove that they could be military motorcycle couriers, able to ride long distances in harsh conditions during wartime. They completed the journey but were turned down by the Army because of their gender.

To mark the 100th anniversary of that ride, BMW and the Indian motorcycle company are sponsoring a three-week motorcycle adventure for women that kicks off July 3 in Brooklyn and will follow the original route to California as closely as possible.
