Earlier this week we posted a trick-or-treat map that Ballard resident John Tynes created to urge families to take their kids around the neighborhood on Halloween.

The map has become so popular in Ballard that we’ve posted it across North Seattle. If you’re opening your doors to trick-or-treaters, add your address on the map above.

Tynes was on KUOW’s The Conversation with Ross Reynolds on Friday afternoon to talk about the trick-or-treating map. You can listen to the interview here.
