The Road to Freedom Bus was in Arizona Friday as part of its 50-state tour to raise awareness for next year's 25th anniversary of the Americans with Disabilities Act.
"We've already hit 18 states and we'll be ending up in Washington D.C. next July," Tom Olin said.
Tom has documented the Disability Rights Movement for the past 35 years with his photography.
His images from his across-country road trip will be archived for the Smithsonian Institute.
"This tour is about raising awareness across the entire country about how important the Americans with Disabilities Act is and just celebrating the wonderful improvements that have been made for people with disabilities since the ADA was passed back in 1990," Phil Pangrazio, president and CEO of Arizona Bridge to Independent Living, said.
The 35-foot bus carries some of ADA history and history from other disability rights and justice issues.
