We have recently moved into a brand new neighborhood. I have offered to have a gathering at my home. Since Halloween is around the corner, I am working around that theme. There are about 15 children coming and 23 sets of parents and neighbors. I need some ideas for GAMES AND FOOD to keep everyone happy and mingling for about 2 hours. (This will be the first time some of us meet each other...we are all new) I am very new to the world of entertaing big crowds, so any advice would be helpful....I would really like for this to be the start of a neighborhood tradition. Thank you so Much, Jennifer
