Being brought up in the Chiltern hills I made myself a promise as at 16 I stood on top of the hill where I lived, the day before I got my 200 Tiger cub, "I will never ride another B...dy push bike again" and all the soap adverts and 'nudge nudge' by the government wont change me now. Anyone who knows the topography of Wales knows it will never be a common method of transport. Well if you have a vote in Wales you know what to do, and the next time a green calls for a vote ask them how many children they have, each one adds 30 tons of CO2 in their lifetime just by breathing, even more if they are push biking up mountains
