My LQS when I lived in California has had mystery quilts complete with a murder mystery, where most of us had a part. They also did a "spa" retreat at the quilt shop.
I know the guild I belonged to in California has members offer classes in their specialties, like mini-seminars. The new one I belong to in Las Vegas is having an mystery quilt option as well as just a sew-in. They also booked a one day long-arm class somewhere near the hotel (that had limited seating).
