"With the mantra these days to combat global warming by reducing our carbon footprint, I decided to tour what is probably the world's most car-dependent big city using only public transportation. Many car-addicted Angelenos don't realize that their city's public transit system is one of the nation's largest; it claims to be No. 3 in terms of passengers per day. My challenge would be to visit the city's wonderful but widely scattered tourist sites without ever getting into a vehicle that wasn't a bus or a train."
