This morning, I cycled about 15 km to visit a friend in south Canberra and about 5 km into the return journey my tyre was punctured again - by the same sort of spike as before. This time I had repair gear and did a nice patch job, blew up the tyre and... discovered a part of the valve had disappeared and the tube lost all the air as soon as I detached the pump! No use returning to my friend as she had no car either so I walked home and ate three slices of Christmas cake. I sketched this agapanthus (about 8" across) as I waited for the patch glue to dry - they thrive in the Canberra climate, flowering in profusion at Christmas time. 20 km cycle, 10 km walk.
