Shannon, this artilce points out all that is wrong with, not only the US, but with many other countries in the world. In Canada, we have handicapped parking at all stores. There are wheelchair accessible ramps. Time after time I see able bodied people parking in the handicapped areas. They are boldly marked.
Blue paint covers the entire parking spot and the disabilities logo is painted on it.
As well, there are handicapped parking signs everywhere. Yet these ignorant people with no handicap sticker on their windshields continue to hog the spots. When I see this happen, I take my chances approach the person and tell them they are parked in a handicapped parking area. This often leads to them cursing and calling me foul names. Good for them.
