While you're watching the 2016 BMW Championship at Crooked Stick Golf Club in Carmel, Ind., you might have noticed that there's a red box that seems to be floating on a small island in the water hazard running along the 18th hole.
As it turns out, it's a funny gag at the Pete Dye-designed golf club.
It's a red mailbox-looking structure that says: GREENS COMMITTEE SUGGESTION BOX. It's really a little birdhouse that has the message painted on the side, letting players and members know where they can go to complain about course conditions and the setup.
The final hole at Crooked Stick is a 457-yard par 4 that has water running all up the right side. In the 2012 BMW Championship, it played as the seventh most difficult hole for the tournament, playing just a smidge over par on average for the week.
