I was in SF for Google IO a couple years ago and was somewhat fascinated by the fog-mist. Also surprised to find that it shows up almost every day. Seems like a better place to visit than live though. Streetcars are a nice novelty, but I can't imagine commuting on that every day.

Anyone know if there are there any cities in the US/Europe that are as clean and convenient (walk-ability and public transport) as Tokyo?
