We had a beautiful chilly but sunny Fall day to go underground in Louisville.  The Mega Caverns serve as the venue for the fantastic Lights Under Louisville.  The train of Mercedes-Benz vehicles made a winding tour through the colorful display.  I'm sure there were more fantastic shots I didn't get but you get the idea from the photos here.  It was wonderful, followed by lunch at the Audubon Country Club, with over 30 members of the Bluegrass Stars and Cincinnati sections participating.
