This tells me that the Nats season ticket sales are up about a thousand per game over last year and up three thousand per game over the low point. It also indicates that despite all of Fluffer's boasting, sales have not yet recovered to the point where they were in 2008 and of course they are no where near where they were when the Lerners bought the team.
If you get a chance, I'd love to see the three lowest attended games per year since 2005 in order to track season ticket sales since the team came to DC.
