Seats 9 and 10 are in the middle of row 7 in section 111. These seats will have a phenomenal view of the action in the attack zone on the east side of the United Center. Unfortunately, views to the other end are slightly obstructed by the glass above the normal boards (the penalty box glass is not as obstructive).

Despite the obstruction, it would only be considered a minor distraction and these seats are a phenomenal spot to see a Hawks game.
