Any end zone upper level seat will be called a 'Touchdown Reserved' section for obvious reasons. They're great seats.
311, row 8 was where I sat for the playoff game against the Baltimore Ravens in 2011. The crowd noise was fierce but the Chiefs ended up losing big time but it was still a fun game to attend. 311 has a great view from behind the uprights, you won't be directly behind the uprights but they will still be in plain view. The best part is when you see the running plays form via the holes that open up for the running back. You can see things from the top level that you just can't see when you sit on the lower level. They're two completely different experiences.

The only downside was the walk to our seats. Other than that, everything from the concessions to the bathrooms to finding security was very easy. Hard to go wrong with section 311; I would definitely sit here again.
