Because everyone eats and having a potluck where you can just show up is so much fun. We've done this almost every Thursday for over 18 months. We meet at the same local park from 5ish to 8ish. Everyone is invited and you can bring as much or as little as you like. The motto is "kids play and parents drink." We have almost 100 families on our facebook group and we get 15-30 families every week. New people come most every week and they are always amazed how welcoming the group is. These weekly gatherings really have made a huge difference in our little community. My dream is to have these all over the country. It would be like an occupy movement for parents.
