Just because the organization owning the meeting had a yard sale, does not mean AA endorsed it. Even if they wanted to, I doubt they could have asked the church or whatever it was not to have a fundraiser.
As someone who has wandered around a number of empty buildings trying to figure out where the meeting was--or at least someone who could direct me to the meeting--I wish there had been some activity going on!
But I do not know if I would be as brave as Serenelife that early in recovery to ask a stranger where the meeting was.
