So the tyre fixer came s'morning and tried and tried to fix my 'chair. No, it was well flat. He had size... and size... tubes but none to fit my wheelchair. Luckily he had another 'chair in the back of his van that had been returned to him s'morning so he was able to leave me that and say "I will give you a ring when we get the bits you need". So Timmy is busy transferring my 'stick holder to the 'new' chair
