Boston has winters that will kill you. Even if you don't die or get frostbite, it's gonna be a bad time. Shelters are often not places to be.

By comparison in SF you can sleep outside all year round with minimum headaches, and tent / camper / van life is an option. Nationally, over time, the homeless will start moving towards places like that.

SF is also more of a cultural fit than Boston.
