Getting around SF with all its hill is a pain in the ass. I once thought I was going to experience a heart attack walking up a steep hill. My knees and ankles killed and my flip-flops broke! It’s true what they say about SF, “The coldest winter I experienced is a summer in SF”, I personally experienced this when I went to Twitter’s 1st ever dev conference. What people may not know, SF is such a small, I mean tiny city, if you sneeze while you’re driving you would drive by it.
