I still check ticketmaster, too, to see if there are better deals. But that's the extent of my searching. Ticketmaster and Tick Pick.
As far as going to this game, I'm not gonna lie. I was freezing at the game this past Sunday. The wind was relentless and I could not get warm. The older I get, the more of a ***** I am with this cold weather crap.
That's another reason I don't want to jump on tickets/lock myself in. I'll probably wait till about a week before the game to decide - after I can see a weather forecast.
