Yes, some people who do have handicapped placards do have a medical condition that is not necessarily visible (i.e., heart condition, arthritis, etc.); however, you don't see these people ready to get their workout on at the local gym, either. So I therefore stand by my original comment ... if someone is physically able to work out at the gym, then he or she can walk a couple extra steps from a regular parking space. Leave the handicapped spaces for someone who TRULY needs it.
