Another legitimate and generous reason to order one.
I did not mean to imply only PWDs should request these. I just hope someone doesn't order one so they can "get away with" parking in the fire lane while they "just run in".
(Total aside here. I used to live about a block away from the Main Post Office in a very urban/suburban area, with extremely limited parking. THe lot had only about a dozen spaces, including two h/c spaces in front of the door. 9/10 times, one was filled by a car with no placard, and someone was sitting in the other while the passenger "ran in". (Of course, I had no car; I walked up.) I'd huff and puff my was past the car, look at the person sitting inside, and say "THIS is why I had to park 2 blocks away?" They'd usually hem and haw, explaining they were just sitting there for a minute. I responded that "that minute" meant someone who NEEDED the space couldn't park there. Still get a kick out of doing that any time I walk past someone "standing" in a h/c spot. Usually makes quite a point.
Just last week, my amputee friend, and I, the Chick w/ the Stick, made an impression on these 20-somethings. It was hysterical. The guy in the back seat wanted the driver to drive us back to our car so we could take the h/c space. My friend just said "I'd rather have my left leg than parking privileges any day!" Priceless!)
