Sat here for the 49ers game this season. The game was off the chain but wouldn't care to sit here again. If you sit in the back rows, you run the risk of not being able to see parts of the field from a number of factors. They put little tv screens up above you as some type of consolation but the tvs are out of date and too small to see. These seats would be ok if it's raining, snowing or extremely hot and you need protection from those things. Were really close to the food and bathrooms too but overall, the experience was just terrible. Much better places to sit.
I've only been to M&T Bank Stadium in Baltimore, so I don't have much to compare Fedex Field to but it's obvious that Baltimore has the better stadium.
