but i just had to pass this on I WALKED YESTERDAY one hundred and eighty feet without any support , no walker, no cane and most of all no wheelchair .I also walked over 800 feet with the walker with only two rest stops .I am starting to believe that I will be back walking . Maybe not as good as before, but after two years of wheelchair It is a areal good sign .Sorry bout being so self centered but I can't help it . GOD bless all bob w.
