Thanks to all for the kind comments..
As to the physical condition of my Dad. He is 67, nearly 68, has survived cancer, and is type 2 diabetic. He tries to stay in as good of physical condition as he can (he was a Marine--Hoorah!!) For those who have seen the disease develop in someone you know how it can affect eye sight, lower extremities, ect. He has the lower extremity problem, that's where it decided to attack him. Fortunate, I am to have him able to go at all. I just miss the long days of meandering through the coverts and chasing dogs...
