Revelers watch from the back of their camper as they take part in the Republic of Texas (ROT) Biker Rally in Austin, Texas June 11, 2015. The ROT Biker Rally, which is celebrating its 20th anniversary, is a four-day event held at the Travis County Exposition Center in the outskirts of Austin. The rally is the largest 'turnstile' (ticketed admission) motorcycle rally in the United States and attracts tens of thousands of bikers, organizers say. REUTERS/Adrees Latif
