The best way to assess friendliness and get a feel for safety in any neighborhood, is to drive there at different times of the day and week. Go grocery shopping there, dine out, get coffee, whatever you normally do in your current neighborhood. You'll get a better feel for any area if you visit during the week during and after business hours, and at different times on the weekend. Also use the crime link provided below, or contact the local police station.
