Si Robertson and nephew Alan at Grace Church in Eden Prairie

Duck Dynasty stars are getting the royal treatment Sunday when they fly to Minnesota for an Eden Prairie appearance.

Si Robertson, his nephew, Alan Robertson, and their beloved neighbor Mountain Man, known to the IRS as Tim Guraedy, will be at Grace Church in Eden Prairie to talk about how a TV show has made millionaires of the quirky Louisiana makers of duck calls.

The 3 to 6 p.m. event, for which tickets can be bought at www.itickets.com, is a fundraiser for Southwest Christian High School in Chaska and Chapel Hill Academy in Chanhassen.

Duck Dynasty Season 4 premiere attracted 11.8 million viewers, shattering cable records.

The Duck Commander warehouse in Monroe, Louisiana, attracts nearly 3,000 people daily, with hopes of catching a glimpse of a Si Robertson.

Uncle Si Robertson may be just as elusive after arriving in Minnesota via private plane.

“We have a bunch of corporate sponsors who made it possible for the Minnesota visit, so they are going to be cranking,” said Si Robertson.

“They only are going to autograph if you have a VIP ticket. There are only a few people who will actually get their autographs.”

Ticket prices range from $30 to $250.
