Our seats in 109 were literally right next to the visitor's tunnel and for that reason, you'll encounter a lot of fans of the visiting team in the area before the game. They will probably be standing in your seats if your tickets were in the first few rows like ours were. Annoying. And the Steelers fans are the first, waving those pathetic little yellow towels around like they're intimidating us.

Even if you root for the Ravens, it's still awesome to see opposing players up close like we were able to (row 7). 109 is great for pictures.
I generally hate sitting in the end zones but my girlfriend bought me these seats so I couldn't complain. It's a comfortable section overall because there are no adjacent sections to your left thanks to the player tunnel. The Ravens run out of the far tunnel to the left of section 109.

If you do get the chance to visit M&T Bank Stadium and aren't tailgating, be sure to check out 'Pickle's Pub' before the game. Amazing food and it's always jumping with plenty of Ravens fans.
