That's actually not much worse than any of the tickets I've seen for tomorrow's game. Still expensive, but comparatively probably one of the better single game ticket deals. It'll almost definitely be a high row (think 11+), but honestly, you can still see the game pretty well from up there. It's a steep climb, but the climb's worth it if you're shprt like me and need the people in front of you to be down low.
Yesterday, they sold some of the reserve tickets (probably the ones reserved for the away team), and I think it was a little over $100 a ticket - but I think you had to be at the North Station box office at noon. No clue how quick they sold out.
