I sit right next to the tunnel and absolutely love it. Those that have said there is nothing more exciting than having the play right in front of you is right. It's a bit tough when the play is away from us, but both sidelines have scoreboards now to look at.
I did have seasons in the upper level, on both sidelines. On one side the sun is out of your eyes , but it can get chilly sooner once it goes down. On the other sideline the sun gets in your eyes, but you stay warmer.
