I have a placard that i hang from my rear view mirror. Outside appearances I look okay. But, I cannot breathe much of the time and have to stop to catch my breath when I am sick. People still look at me, when I park there, like they wonder why i have one and the few times that people have said anything, I just look at them and say, Look, i need new lungs, what's your problem? or something to that effect because it just irks me how people judge you if it is a disorder they cannot see. My sister has Multiple Sclerosis and uses a walker. Does that mean that I have to use one to park in a spot.... NO!! I dont know your laws in the state you live in, but in Indiana, the doctor fills out the application for you and you take it to the License Bureau. We have a choice of a placard that can be hung on the mirror or a license plate. Both are good for some odd years. Good luck!
