I've got competitive tree felling, log flume riding, and caber tossing. There's archery and boxing/wrestling. There's chess, there's a pie eating competition, even an obstacle course.

That gives me all the mechanics I'm interested in settling the players into immediately - ranged and melee attacks, skill checks, saves, skill challenges, and roleplay - but I need more fun side bits to help set the scene. There's food stalls, a bar, a little gambling, and I'm probably going to have a children's storytime place the players can go and make up wild tales, but what other kinds of flavour do you pepper around your festivals for the players to interact with?

The campaign is Abomination Vaults for anyone with setting specific ideas.
