Sometimes, when Mike Ervin sees other wheelchair users about to board the bus or enter a train station in Chicago, he wants to catch up to them and say, “You’re welcome”. Because 30 years ago, much of the accessibility that people with disabilities encounter in public transportation today — lifts on buses, elevators at train train stations — didn’t exist. There were also no curb ramps, and buses would drive right by people in wheelchairs without stopping. But Mike Ervin, who has used a wheelchair all his life, fought to change all that. In this week’s episode we look at the history of the fight for disability rights in Chicago.
