The good news is, I know just where I'll be able to have the knee-brace prescription filled. It's a matter of blocks away from where I get physical therapy.
The not-so-hot news is, by the time I got done at physical therapy this afternoon, said durable-medical-goods provider was closed for the day. Drat.
At least I was able to copy their phone number and business hours down from their sign. I'll call them tomorrow and find out if I have to make an appointment to come in.
