I note that the author is a New York import, willing to take some risks to enjoy the best of Alaska, it seems.  My comment is about how native New Yorkers survive, acknowledging that under a recent mayor the city has cleaned itself up a lot.  Evidently, New Yorkers know how to navigate past danger by being alert to it.  Men, especially, look ready to defend themselves.  Are well aware of places and times of day to beware.
