I have just seen the most ridiculous thing. I was out riding today on the Mineral Tramway in Cornwall. It's a track that runs between Portreath and Devoran and crosses several roads en route. At one of these junctions a guy on a bike came hurtling down a quite a steep hill with a chid in one of those child carrier/rucksack type things on his back. She couldn't have been any more than 2 or 3 and was so high in the thing that her head was higher than the cyclist's and she had her hands on his shoulders. Don't think her helmet would have made a lot of difference if someone had pulled out in front of them!
