If you're a fan of Busch Beer, you might want to venture to a National Forest for a chance to win a year's supply of the beer if you find a medallion hidden in a National Forest.

The beer brand is also helping the National Forest Service by donating a portion of the proceeds when you by a specially-marked 'Outdoors' case of the beer, and a dollar when you don't skip a Busch Beer ad on You Tube.

As far as a year's supply of the beer you could win (or, $480 depending on your home address location), you need to visit any National Forest and hunt for special medallions that have been hidden in trees across the country. Six of these gold medallions have been hidden, and three have already been found. You'd better hurry though because the promotion ends November first.
