14. NRG Stadium
Home of the Houston Texans
Coolest feature: The two-paneled retractable roof, which takes seven minutes to open or close and helps immensely during Houston’s late summer scorchers.
Fun fact: For the annual Houston Livestock Show & Rodeo, some 5,500 cubic yards of dirt are brought in to cover the stadium (another 2,600 cubic yards cover the livestock area and horse arena). After the rodeo, it's trucked out and saved for next year.
Hard to believe NRG Stadium was the first NFL facility with a retractable roof, considering it opened in 2002. That just seems to be how Houston rolls -- the city also invented AstroTurf, which the stadium began reppin’ in 2015. Built to function as an intimate indoor arena but have the feel of the open air, the stadium rocks open-to-the-field concourses and a 71,500 capacity, with 8,200 club seats, 187 luxury suites, a bunch of club lounges and bars, two Killen’s barbecue stands, and a Texans team store at which you can purchase J.J. Watt jerseys while wiping the tears from your eyes. Two colossal, 50-feet-by-277-feet HD screens sit pretty above each end zone, pumping up a crowd that admittedly plays home to a mixed bag of NFL fans (is anyone actually from Houston?). You’ll find the loudest home-team crew in the “Bull Pen,” a raucous bleacher section behind the north end zone. -- Brooke Viggiano
