“You’ve got great universities like Pitt and CMU and they invent things, and now we’ve got Mill 19 and Hazelwood Green, which is like the development flavor. Between Hazelwood Green and Neighborhood 91, that’s 400 acres of development and production capability. And I would be surprised if that’s matched anywhere in North America.”
