Michele Kaplan wants us to mind the gap. The space between a subway car and the platform might not seem like a big deal if you’re bipedal, but it can pose a safety hazard if you’re using a wheelchair, cane or walker. Michele got fed up on July 10 when she tried to board a train in a supposedly accessible station and her powerchair got stuck in the gap. She was forced to rely on “two burly-looking passengers” to get her chair out of the doors and onto the train. When she got home, she decided to fight back. Michele started up a Tumblr and set up a petition, and she’s been putting the word out ever since.
