A reversed flipper mode called "Beer Cart Bonanza" or something to that effect would be cool. There are beer carts on pretty much every golf course after all, LOL. Hitting one target or a series of targets could each add a "beer" to your beer total. Once you get too many beers, you get the reversed flipper multiball or a reversed flipper mode. Not that any one encourages being drunk on a golf course of course.
Just a thought.
