From Morgan Bast at the Buzz blog:
[Vail Resorts] announced this morning that they have entered into an agreement to acquire the Lake Tahoe resort, making almost eight ski resorts accessed through the Epic, Epic Local, and Tahoe Value passes. As of today, Kirkwood passholders will have access to Heavenly and Northstar California, and Vail Resorts passholders will have access to Kirkwood. All pass options and information can be found at bestoftahoe.com.
Not too shabby.
