Why not sometimes a fishing comp event...?
Some drinks, some food, and a fishing pole !
An admin to see results, or a referee.
A free fishing pole + bag for players who don't those tools.
15 or 20 or 30 mins to fish, and the number 1 will have a cool gift... something about the fishing spirit (some beer, red wine, a gold fishing pole, a beautiful green camo outfit...)
ps : sry to post here, I haven't found any subjects like that around
