Planning to attend the Oregon Truffle Festival at the end of the month? Forget it. “The Epicurious Experience” package ($625 per person) is sold out. So is the “Epicurious Gourmand” ($695), the “Gourmand at the Villa” ($750) and even the “Epicurious Grower” ($1,050). And the waiting list is hundreds of names long. Founders Charles Lefevre and Leslie Scott started the Eugene festival in 2006 to celebrate, promote and educate people about wild Oregon truffles.
