Sorry Bill, my comment was aimed at those who laugh at my tyre replacing mishaps, not your good and caring self:-)
As for the state of my back, well it's still buggered I'm afraid :-( Day to day stuff is OK and bearable, but walking over a mile is nasty and running/tennis/cycling a definite NO NO! As for riding Dolly, I can manage the comute, but wouldn't want to go much further.
Doc has refered me for an MRI scan, but said "Don't hold your breath, this could take 6 months or even longer" Been having physio, but doesn't seem to do much good, and I can't afford private treatment, no matter how good it might be.
Keeping cheerful though, and reading a lot, but don't expect to hear of me riding very far for a while. Take care matey, and make sure you look after your back! (that goes to all of you)
