I love this and have been longing to start a similar tradition in my neighborhood. My problem is getting people to actually show up. I find time and time again people express interest in texts/online and then flake out. Even getting three women to hang on my porch and drink free wine after our kids go to bed is an uphill battle. They actually show up maybe every other week. It sounds like you have a fairly loyal group! Kudos for taking initiative and so glad it's working out. In our increasingly disconnected world, these collective rituals are so important.
