Surprisingly, Linda said her knees don't hurt at all from the 5K run yesterday. She was sure that she would be limping today. (You are not supposed to run with an artificial knee, but she thinks she is the Bionic Women.) Carol sent a photo that was taken with David Cook before the race. If you have not seen his interview after the race on Youtube, go watch it. I guarantee you will tear up.
Of course, Linda cries at every emotional event... happy or sad.
