Question about ND Stadium Ticket Scalpers

I'm highly interested in making the trip to the game on Saturday, but I'm having a hell of a time finding tickets for under $150-$200 anywhere (eBay, Stubhub, craigslist, etc).  I'm considering driving down there and just trying to buy tickets off scalpers, but I've never been to South Bend for a game so I don't know what the scalper situation is like.

So, to anybody who's been to Notre Dame Stadium in recent years -- how abundant are scalpers around the stadium?  Would I have a decent shot at a deal?
