While I'll skip the details of my injury, it has become more apparent to me that there is a shortage of handicapped access, and attention paid to accessibility. Whether it was reaching over my head for the automatic paper towel dispenser in a public restroom, or not being able to reach the spigot, the worst experience I've had thus far was the wheelchair getting stuck in a pothole, inconveniently situated directly next to the curb cut. Didn't see it, and, luckily, a knight in shining armor lifted the chair with me in it out of cavity.
Disabled folks need to be able to ambulate, see, hear and have access. They need to know that the non-disabled are on their side; to be ready to assist whenever possible. You'll feel better; they'll be better. It's the right thing to do.
