Oh my that sounds like such fun! I don't have any GD's and the GS's age 3 and 1 are too much to handle together. DH and I will go over on Sunday (making Halloween cupcakes to take) and help them get dressed up for Trick/Treating. Take pictures and hand out candy until they get back. Maybe next year I can plan something for the 4 yr old that MiMi and PawPaw can do with him. :) Enjoy your GNO party!
