I ride 10,000 per year here in the California desert. Summer afternoon temperatures here are above 100F from late May until late September. Totally car free. My last cars were a 1965 Vanden Plas Princess, 1966 Rover and a 1968 Jaguar XKE. Cars are a form of obsolete machinery. They make you physically and morally weak. I tell people that they run on dead babies. You don't see the dead babies and you aren't required to harvest them yourself. But trust me, the oil companies and politicians harvest them for you.
