"Good choice for bringing the family"
Located close to the entry tunnel and in the lower portion of section 239, seats here would be a great option for bringing the family. The seats are protected by the club deck above, and the views of the field are very good from right at the goal line. Guard rails didn't obstruct my view at all, but it was likely an annoyance for the people sitting in the first row.
The concourse was a quick trip away for restrooms and concessions, and also had one of the more permanent and official looking Redskins teams stores just outside (most others I saw on the main concourse looked like temporary tents that only get set up on game days - see pictures). I got to the stadium early and also saw that some of the Redskins Cheerleaders were outside the nearby team store giving autographs and taking pictures with young Redskins fans before the game.
Best for... bringing the family
