Decided to take the family out to a Nuggets/Timberwolves game on February 20th, 2012; a game that went into overtime. Our tickets were only around $10 a piece so it was a bargain. But these are the epitome of the cheap seat nosebleeds. They weren't bleacher seats which is what always comes to mind when I think cheap seats. But bleachers may have been more comfortable.
There just wasn't much space between each seat.

The idea, since I have two small children was to buy cheap seats in case they wanted to leave the game early and I wouldn't have wasted a bunch of money (you never know). I will say that when you sit that high up, it's impossible for small children to get into the game as opposed to sitting close to the benches and them seeing the huge players up close.

I enjoyed the experience but I don't have any plans on sitting in the upper arena corners for future Nuggets games. It's too big of an NBA arena and the three levels of seats puts upper level patrons at a disadvantage.
