Barrett, who also serves as the vice chairman for the National Forest Foundation, is offering to host the winner of an Earth Day charity auction on a Montana ranch.
The highest bidder and a guest will receive a three-day, two-night stay in a private cabin at the Triple Creek Ranch at the base of Montana's Bitterroot Range. The winner will have the chance to go fly-fishing and horseback riding with Barrett and join him for a gourmet meal.
The minimum bid is $25,000 and bidders must prequalify. Bidding will open April 16 and close April 26. Proceeds will go to the National Forest Foundation and its efforts to conserve forests, watersheds, wildlife habitat, and recreational resources.
