My brother and I hosted a golf tournament to celebrate graduating from college. It was 18 holes, drink a beer a hole, with a BBQ and three live bands afterwards.
Here is the introduction from the old website:
Trail Ruts Golf Course and Larson Park Campground is hosting the first annual Keystone Classic Invitational Golf Tournament in Guernsey Wyoming. The festivities kick off with an 18 hole 2 man scramble with one simple rule: Drink a beer on every hole (except hole 6). A one time entry fee of 30 dollars per person will pay for everything including green fees, cart rental, club rentals(if needed), camping, and gas for the jam session bands. In other words, 30 bucks gets you in the door for a night of golf and drunken ridiculism and a place to crash when it is all over.
