Social documentary photographer Carlan Tapp embarked on his 2,450-mile, fundraising motorcycle ride in May and has been documenting and blogging about his journey ever since.

As a means to raise money for "Question of Power" — a nonprofit organization dedicated to raising awareness of the effects of coal-fired energy — Tapp pledged to ride an American-made motorcycle from Chicago to Santa Monica, Calif., along historic Route 66.

Scheduled to finish his journey on June 14, Tapp has encouraged supporters to join him on his long journey. He will also offer a photography workshop in Texas and New Mexico.
