I realize that all things considering this sounds kind of lame, but I'm kinda sick of it being cold. And yes, it's only in the low 50's in SF.

The problem is that nobody in California thinks the weather is going to be anything but perfect so the place isn't really built for handling any sorts of non-perfect weather. As a result, with the exception of people who ski, nobody really has any winter clothes. And most places that aren't brand new aren't really built for cold weather so apartments are really drafty. I'm in my fifth apartment in this city and all of them got butt cold at night and none of them had great central heating. So basically, you're stuck in a cold apartment until you go out into some cold weather wearing clothes that aren't thick enough to go to a place that's either over-heated (the bus) or perfectly heated (office building/stores).

Which, again, doesn't sound bad but when you're home all day in a cold, draft apartment and then go out and take a walk in cold weather, it's not so fun.
