One highlight item up for bid is the chance to meet Carrie Underwood during one of her 2007 concerts. Fans may also bid for luxury suite tickets to see a show from Tim McGraw and Faith Hill’s Soul2Soul Tour 2007 or Keith Urban from his current tour. Also included are autographed items and a chance at a country music lover’s dream vacation from the Country Music Association. To claim any of these fabulous items, go to charitybuzz.com.
