Does the Thursday evenings @ the Dog&duck pub have a regular turnout? What about the Sunday mornings @ romeos? How would I recogize the group? I'd hate to show up at some bar going around asking various strangers "are you the atheist group?"
We have three events weekly. You've mentioned the Happy Hour and the regular Sunday meeting at Romeo's. We also have a get-together after the TV show on Sundays. You're welcome to come down. In all cases, the host/hostess/waitstaff knows us. We're also usually the largest table.
If you're shy, just say "Are you guys with the ACA?" Or "TV show" for the dinner.
Each group has a somewhat different crowd.
Come on down!
