I've never heard of city hours for T or T'ing. We start seeing kids once it gets dark and we close up around 9-9:30. Once we have spans of 20 minutes since we had a t or t'er, we turn off the light and watch TV. My kids go out once it's dark and then are home to help hand out to the older kids (mostly middle school and teens). If you are wearing a costume you get candy at my house
