The Chicago Cubs are opening an $84 million spring training facility in Mesa set to open by the end of the year. Built on the site of the the old Riverview Golf Course, the complex will include a 15,000-seat stadium with six suites, six restroom and concession areas around the concourse, and a 65,000-square-foot clubhouse and training center. Several areas are being built for groups including a left field rooftop party area, party decks along third and first bases, a right field party tent, and a kids area. Other features include a 120-person theater in the clubhouse, a picnic area, and a site for food trucks. Design touches include a cantilever roof, and light towers recall Chicago's Wrigley Field.
