MILWAUKEE (CBS 58)--One of the best times to take a Miller Brewery tour is right now during the "Miller Valley Holiday Lites."  You can catch 700 thousand light displays on this free indoor/outdoor walking tour.  The tours run every 20 minutes Friday and Saturday nights through December 22nd.  You can even see the famous Miller Caves up close and personal.  A few beer samples round out this festive draw, now in its 15th year.

The first Lites tour starts at 4:40 in the afternoon.  The event ends at 9 in the evening.  You start out at the Visitors Center off State Street where you'll notice Miller's famous Christmas tree made up of 225 kegs!
