Section 512 wasn't bad. Could see the whole field and all of the action. The fireworks that took place when a touchdown was scored was pretty cool. Also loved the white Bronco statue on top of the South endzone's jumbotron.
The seats were comfortable although the metal can cause the situation to become slippery if rain or snow takes place like it did the game we went to. And the proximity to the Light Rail and The area buses/taxis are a great setup as well.
