I was so disappointed when I first saw the circus tents in St. Martial and found nothing but Carnie mobs. No midway games, no rides, no fortune teller harking for some of your infamy, no bearded lady show, no strongman competition... nothing but tents. Redo that area (do we really need more Carnie mobs doing nothing?), and copy a smaller version to blue side somewhere.
Edit, add: those specialty shows could have a one mission contact inside, something that could be written up by players through AE and converted to real game missions.
