I think they were filming it, from what I could see in sec. 110. The same handheld camera type (with two grips) used to film Atomic City was used for the show.
It looks like up to one percent of the seats in the premium sections are up for resale with a huge markup. Years ago before presales and codes etc, the percentage was a lot higher.
Site says:
"There is a 2 ticket limit for the Fan Club Presales. There is a 4 ticket limit for the Citi Presales. There is a 4 ticket limit for the Verified Fan Onsales."
I assume this means up to 10 per verified fan for a show.
They can sell only so many VIP packages and they convert the remainder to regular seats. There's still plenty of opportunity as more shows are added. I had no problem getting great side seats in 2015.
The travel to and parking can be a pain at fedex field, but the reserved lot should help a bit. Hopefully the rush hour traffic won't be too bad (it was last time). They tend to schedule the DC shows midweek, possibly so that politicians etc can attend.
