IMHO, Soldier Field is a masterpiece of stadium renovation. The cantilevered video boards, the rake of the triple-tiered east side, the bank of suites. It looks great because it looks so different from the cookie-cutter bowls in so many other US cities.
Had a look-see at the new Vikings Stadium? That's gorgeous!
