I also find it curious that safety and sanitation aren't referenced. I by no means have all the answers; however, I am sure my main reason for leaving San Francisco will be along the lines of these things. I've had traumatic experiences living in this city and I am 6 ft male that lifts weights often (I'm just trying to imply that some people most likely get harassed even more than I). I wish I had more of a capacity to help this city rather than leave.
