But I keep mom's placard in my glove box for picking her up. The other really weird thing about some parking lots is the relative abundance of disabled parking places relative to the small size of the parking lot. I must confess to misusing her placard once when there were eight disabled spaces open in a lot where every single other space was taken. This was a small strip mall, not the type of place where you'd expect physically disabled people to congregate.
I've seen a lot of this too. The size of the placard population is so large now that some parking lots have allocated very substantial chunks of their space to disabled people. I'm all for making life a little easier for the disabled, but for many people it's just another way to cheat.
