Boise State is famous for its blue turf at Albertsons Stadium; it gives the Broncos a distinct identity and can serve as a welcome changeup for college football viewers. Unfortunately for Boise, the blue turf is often flooded by geese in the offseason who think the blue turf is actually blue water.

This probably wasn’t an intended side effect of sporting blue field turf, but it is certainly a humorous one.
