Lady Antebellum, Darius Rucker, Zac Brown Band + More Play Country Thunder in Wisconsin

Lady Antebellum were just one of last weekend's headliners at Country Thunder in Twin Lakes, Wisc. The four-day festival included almost two dozen performances from superstars like Darius Rucker, Martina McBride and the Zac Brown Band, as well as up-and-coming stars like Easton Corbin, Steel Magnolia and Sonia Leigh.

Heat was a concern with temperatures soaring into the mid-90s each day. Thousands of campers and country fans still filled up the venue, cheering on their favorites which also included legends like Lorrie Morgan, Neal McCoy and the Charlie Daniels Band. Lady Antebellum's set was a highlight; it included Hillary Scott sporting a brand-new engagement ring which she was more than happy to show off. You can see Lady A and the rest of the 2011 Country Thunder lineup in this set of pictures from the event.
