I met Gary north of Harrisburg, PA today. He was at the doctor's office and she said he could continue walking. His foot is really swollen (to the point of not being able to see his ankle bones) so hopefully just walking 4 miles today and not too many tomorrow will help. He is soaking it and sometimes having it on ice. I won't be driving to see him after this visit. This was about 8 hours. It will be a long few months but it will be over before you know it.
