I have a friend that has a permit for disabled parking spaces. And yes, he really does need the privalege.
When we go someplace together, I usually drive. I am willing to drive to the entrance of the event, then park in the 'Outback' and walk to the entrance of the event.
My friend insists that we use a parking space for the disabled. I don't feel right about taking up that space. I can do the walk and then someone that has a disability could use the parking space. We have had some discussions about this and he does get a bit irritated so I drop it. I don't really know how to get around the issue.
