My son is in his second year at RPI right now!I think this is indeed their first stadium from the ground up. The Etihad was built for the 2002 Commonwealth Games. As far as I can tell, all the other clubs they bought or bought into were already playing in their own parks, although CFG has built a lot of ancillary facilities (academies, that kind of thing).
We're kind of their baby, the team they created from scratch at the start of their expansion into CFG. And NYC is by far the biggest city any of their teams play in. I can't imagine they'd come light.
(Ferran Soriano got his MBA at Rensselaer Polytechnic Institute not far from where I'm sitting, too. I'm sure he has a soft spot for the Big Apple. LOL)
