Not really, I was searching for the word "camping", came across it and thought of giving you a "gentle reminder" 🙂 and looks like it triggered a good conversation though.
I am in for any option of those you mentioned, the challenge will be coordinate schedules as end of year brings us to multiple activities (personal and work related), therefore planning for Jan-2022 might be a good idea, but nothing stops anyone for an impromptu decision to go camp, sometimes it is the best approach!
Perhaps publishing it as a drive, with a limit to a number of cars, might draw attention and commitment?
