Pass a flashlight around the circle. Whoever holds it answers a question, then hands it on, and anyone can pass it straight along. Start with the easy openers while the fire is high and people are still eating. Move to the later groups once the circle has quieted down.
With kids around the fire
Young kids can answer the first group, and they can ask the questions too. Let them pick who answers. Stop before the late-night group if the youngest are still up, or let them listen.
When the fire burns low
The last group is slower. One or two questions can carry the rest of the evening, so there’s no need to work through them. If someone gives a short answer, let it stand. “Who’s someone you’d love to have around this fire tonight?” may bring up a person who has died, so read the group before you ask it.
If a family story starts at the fire and you want to hear the rest, the questions for grandparents pick up where a campfire leaves off. For the drive there, try road trip questions.
