Hey all... worked on this for about a month and a half, was a nightmare at some points to get completed, but it was well worth finishing.  I'm not sure exactly what scale it is to, however I used a seating chart online and basically used that as a framework to help get a good amount of the foundation set up.  Approximately 9,000 seats, give or take, real MSG has about 18,200 or so...  More info in the description, but hope you enjoy!
