Had a sign out and everything. All the little LDS kids in our neighborhood participated together on Saturday. Thought it was great. Then a little neighbor girl knocked on our door on Sunday evening, despite the sign. I still cringe that I turned her away. It's not that big of a deal, and I certainly will let my 9 year old trick of treat on Sunday, and will not be turning anyone away again. (We're definitely not in an LDS community).
