You and Yammer have a good point I didn't think about! Haven't seen that myself but I'm sure it happens! I think the issue is more and more handicapped permits are being issued and for the most part to deserving individuals, but in some cases perhaps maybe not so much!
Myself I don't mind too much as whether I take 1 step or a thousand my feet feel the same but some people are a lot worse off i.e. wheelchairs, crutches, walkers, canes etc. and deserve special consideration. Maybe there should be two classes of handicap parking...
