Last time when I visited SF, my local friend never go to / hear about de Young Museum or Yosemite 
I think that most visitors want to make most out of their short trip, sometime once of life time. But the local see that just part of their life, and nothing is excite about it.
For my self, I start to take more Melbourne photos, and the 'local' start to ask me if I'm in holiday or not 
BTW, my heart go to Oslo victims...
