Mark got this back in April. We'd been to see the doctor and I mentioned how difficult it was for him to walk to a building from a far parking lot, toting a heavy laptop bag. He'd been able to attend a weeklong class. Just being out of the house for that many hours, that many days in a row, is tough for him. The doc got him this placard for the car. So, he's officially "disabled" at least as far as parking goes.
