Does any one know how the row numbering works in the east upper? For example section 637 row CC. How far up is that? Does it start at row A meaning that row CC is like row 29?

To the best of my knowledge.....you are correct.
The rows start at A.

looking at tix on ebay and trying to decide if its worth it? here's the official seating guide

I'm at 641 BB for the VT game...face value is $45...BB, i will assume is 28 rows up.

The yellow, wider seat with a back and armrests run from Row A to Row K. (I believe this is for all Upper East sections.) After that, all seats are bench seats and a little more narrow.

You'll have two options to get to your seats. You can take the sole escalator which often breaks or you can walk up the ramps to the top. Either way, make sure you enter the stadium an hour or so before the game.

Hope your not afraid of heights. :hihi:

that is up there...i had a friend once describe those seats as "...up there with baby Jesus."
