My husband was blind and we had handicap license. He sat in the car most of the time when I would go into the stores.
I always parked in the closest to the door, because he was afraid that someone might try to attack him if we were further out in the lot.
I never had a moment of guilt.
Bravo for you, because then it would be clear that there was a legitimate reason. Those of us on the outside of this, though, are the ones who see the teenager pull up in a sports car, pop the card from the glove box to the mirror, and walk inside to buy DVD's. I just want every single person who deserves that spot to get it...because it is free of those who would misuse it.
In My Universe, anyone who scammed the system would have to make a public apology for it. Those who are awarded the spaces should be the ones using them.
