Where Would States Be?
The hardest question to address if states were to all move to one location would be "to where?". You would need an extensive amount of field event venues to fit the meet into a weekend. That definitely narrows the amount of locations in a hurry.
From a just track standpoint the best facility would be UVA but we can rule that one out until it receives permanent bleachers and bathrooms.
The next candidates are Todd Stadium, Hampton U, Norfolk State, Sports Backers Stadium, Darling Stadium, U of Richmond, George Mason, CNU, and William & Mary.
The best venue considering the need for bathrooms, seats, multiple field event venues, parking, and of course being a nice facility would be the College of William & Mary's Zable Stadium.
