121 is located in a string of sections called MVP boxes. But don't let the name discourage you; these seats are very affordable to the average fan. For most games; they're in the $40-$50 range.

Because this is also a venue for an NFL team, the foul territory is huge and you're no where near as close to the field as what the seating map suggests. These are still decent seats no matter which row you get; I have sat here for tons of A's games.
