San Francisco is pretty magical, and if you've never been there it should probably be near the top of your list. But it's definitely a city of contradictions. Don't know what I mean? Let's see here.
You feel both extremely poor and extremely rich.
You feel like your being so "green" but also like you're really destroying the environment.
You're too old to be there, but too young to not. If that makes sense.
Feel overdressed? You might be under-dressed. Or not.
You feel inferior from all the wonderful things around you, and also overwhelmingly inspired.
Like I said: It's the city of contradictions. You can't understand it until you've experienced it. So what's stopping you? Just go.
