Thanks we will turn all lights out when we leave.No you do not have to give out candy. The MNSSHP officially starts at 7 pm but you can enter the park at 4 pm so either way you won't be at the Fort that evening. Just turn all your outside lights off. Trick Or Treating starts around 6 pm. They always recommend that people giving out candy to set up a table or chair at the end of their site. They do not want kids going door to door knocking.
