"It really pays tribute to the dome, but it produces a tremendous amount of usable green space," Shafer said. "It produces a park right here in the middle of NRG Park and that's something that we don't have at this point. It's something that's tremendously usable by the Rodeo. It's something that's tremendously usable by the Texans, but more importantly it's usable by all of the other people that come into the grounds. All of the promoters and the organizations that do shows here. It is affordable."
