Carolyn would like me to pass on her thanks for all your kind remarks, sorry it's taken so long, but I've been very busy just lately with one thing and another.
As a footnote, Car's knee injury has been really bad since the walk, a visit to the doctor's proved useless, told to take more paracetamol and rest. Asked if she could have another x-ray, the doctor said she'd had one recently, recently being just over 2 years ago. Aah well, I suppose that's the way things are in this country just now.
