My grandmother is in town from Colorado for 10 days. Today she stepped out of the car wrong and twisted her ankle. She doesn't want to go to the doctor - but she's having a hard time getting around on her foot. It's not swollen - but she really seems to be in pain. I'm trying to find a place that rents wheelchairs - that's open on the weekend. Does anyone know where I could get a wheelchair for a few days without waiting until Monday?
