Bring your lawn chair, put on your mosquito repellant, bring your favorite fireside beverages, but most imporantly -- bring traditional ballads to sing. If it tells a story, doesn't necessarily have a chorus, and has been sung by people for quite some time -- bring it to the firepit. There will be light food available but the emphasis will be on singing and feeding the fire. Listeners also welcome.
So far the weather forecast looks good -- a clear, dry night, about 66 degrees. Let me know if you're coming by sending email to firstname.lastname@example.org.
