As you head to or return from the "Dilly in Chantilly" at the Ski Chalet this weekend you might also want to stop in at Willis Ski Shop in Fairfax, just off Routes 50 and 29. They are having a big preseason blowout! Here is the link to their site:

Willis is fairly new in Northern Virginia, but for those that ski at Seven Springs this is the same Willis ownership.
Enjoy,
