Never played a game on a bus trip before....
but how about people just telling a little about themselves to everyone. If they talk loud enough and everyone's quiet, maybe they'll be heard. Not everyone needs to say something. Pick a row and seat number.
Or how about you coming up with ICE BREAKER questions that people need to ask each other. When did you start quilting? What's your favorite thing to do with quilting? Least favorite?
Or ask very general questions like Who's been quilting the longest? Shortest? Who's traveled the farthest to go to a quilt show? Who's going to their first quilt show today? Maybe have little prizes.
Maybe the bus ride home will be quiet because everyone is quiet or reading a pattern.
I'm sure it'll be fun.
