MINNEAPOLIS -- Historically, games in Minneapolis between the Minnesota Vikings and the Green Bay Packers have crackled with a kind of intensity not found in the Vikings' other home games. The westward migration of Wisconsin natives to the Twin Cities, coupled with Packers fans who snatch up tickets for the game and travel to the Twin Cities for the weekend, typically means the Vikings' home stadium has a sizable contingent of opposing fans who arrive intent on making their presence felt.

Packers fans have been aided in their quest in some years by the availability of single-game tickets, but this year, as the Vikings open U.S. Bank Stadium, their tickets are popular enough that getting into Sunday's game might not be quite as easy -- or, at least, not quite as cheap. The Vikings announced in August that 60,400 of U.S. Bank Stadium's 66,655 seats were committed for the full season, and the remaining single-game tickets were sold out. Some of those single-game tickets for Sunday night's matchup could have wound up in the hands of Packers fans, but there weren't as many to choose from as in some years.

It's on the secondary markets, then, where Packers fans have their best chance, and even some of the indicators there suggest they might have a harder time turning U.S. Bank Stadium into Lambeau West this year. StubHub spokesperson Cameron Papp said the Vikings-Packers matchup is the second-most popular on the ticket reseller's site this year, behind last Sunday's New York Giants-Dallas Cowboys game, and the median ticket on the site is fetching $350, or more than double the median of any other Vikings game this year. What's more, while 17 percent of StubHub ticket sales went to Wisconsin residents for the Nov. 23, 2014, matchup between the teams at TCF Bank Stadium, and 13 percent of the tickets were sold to Wisconsinites for November's game in Minneapolis, only 10 percent of the tickets for this year's game have been shipped across the border.

That's still more tickets than Illinois or Michigan residents typically purchase for the Vikings' games against the Bears and the Lions -- Illinois residents snapped up 7 percent of StubHub's inventory in December for the game against the Vikings, while Michigan residents bought 4 percent of the tickets for the Lions-Vikings game in September 2015. Still, whether it's a desire to attend the first regular-season game at U.S. Bank Stadium in person or a resolve to keep "Go Pack Go" chants from becoming a prominent part of the NBC soundtrack Sunday, plenty of Vikings fans say they're going to be there themselves.

"Although I could sell them for a premium (seats in my section are going as high as $2,000 a seat), we're keeping them because I'm not letting a Green Bay fan take my seat," wrote Adam Burtness, a Vikings fan with $200 face value tickets on the 50-yard-line in the FMP Club. "Can't put a price on keeping the stadium in purple."

Still, for some Vikings fans, the cost of seat licenses at the new stadium, coupled with the demand for tickets to the headlining opener, made selling their Vikings-Packers tickets a shrewd opportunity. Minneapolis resident Brock Trautman, who paid for a pair of $2,000 seat licenses for two seats in Section 231, said he sold the pair for $500 apiece to the Packers game, and offloaded all of his tickets for the first season except for the Vikings-Colts game on Dec. 18. Trautman said he already recouped 110 percent of his seat license money from the sales, and will go to games in future years.

David Nordby, a Vikings season ticketholder who lives in Green Bay, wrote that he decided to pass because the Sunday night matchup made it too hard to get back for work the next morning. He sold two seats in Section 344 for $338 apiece, and got $409 for his two seats in Section 138, adding the price for the tickets dropped somewhat on StubHub and NFL Ticket Exchange after Teddy Bridgewater's knee injury in August.

"It kills me not to be there," he wrote. "I would not sell to friends who asked in Green Bay -- mainly because they wouldn't pay enough, but also because (I) want to keep it purple in there. I can't stand the 'Go Pack Go' chants when they're in Minnesota."

The caveats, before Vikings fans envision a stadium united in purple against their team's fiercest rival, are these: Enough Packers fans live in Minnesota, and elsewhere, that the drop in secondary-market sales to Wisconsin residents doesn't mean green-and-gold party-crashers can't get in (it's also worth noting that only 41 percent of StubHub's sales for the game went to Minnesota residents, after 52 and 51 percent for the Packers game the last two years). And the Packer faithful that did spring for tickets to the game are likely to be a vociferous bunch -- the 7:30 p.m. Central kickoff does leave plenty of time for, shall we say, pregame refreshments.

But there are enough Vikings fans who snapped up tickets for U.S. Bank Stadium's first season, and enough of a resolve among some of them to prevent a bipartisan crowd, that the green-and-gold disruption of the stadium's purple palette could be more subdued than usual.

Maybe.

"Bought two tickets in (the) third level from our long-time contact/seller from Craigslist. Paid below market value, but I'm sure well above face value," wrote Vikings fan Zach Schultz. "The seller gave us a break on price to what he could have gotten on Craigslist, StubHub, etc., because he knew we were Vikings fans, and he refuses to sell his extra tickets to Packer fans and can't stand it when other people do so."
