Bicycles, snow

This isn't the kind of place where people buy - or, so far as I've seen, sell - studded bicycle tyres. The few days a year of proper winter weather mean moving from seeking quiet roads to seeking busy ones, where there are gritters and hot-bellied cars and the ice doesn't set in so much. It also means avoiding hills, so that if the ice has set in I can be relatively under control when things go wrong. Peckham is better for this than Sydenham, which was the far side of a very big hill. The problem is that any weather bad enough to make cycling on main roads really unwise will probably also stop the trains and buses, and my boots aren't great. Tomorrow will be the test. Wish me luck.
