The only place in "Sea Town" that I would feel unsafe in are certain blocks in the Rainier Valley or Central District at 3AM. I did enjoy living in Brooklyn more than living in Belltown, though.
I lived in Philly at the height of the crack epidemic w/all kinds of homeless people walking around. I too used to tell people not to be afraid of the city. But times have changed and personally, I'm tired of homeless, I'm tired of fending off weird men, young kids who won't work, addicts, crazies, etc.
Will they hurt you? Who knows? Many won't. Some will. I just got tired of running the guantlet. Maybe there's a reason people my age move to gated communities.
btw - i'm sending you freepmail
