Dubbed "the Ultimate Secular Festive Singalong," Yule Rock at Community Forge celebrates the season with nondenominational tunes. It's a community-driven event, with a potluck dinner and arts and crafts. The event is put on by Sunday Assembly Pittsburgh, a "secular community that celebrates life" and builds "community throughout the Pittsburgh area to improve lives." If that sounds like your cup of tea, this is a great way to introduce yourself.
