The Pit, Albuquerque

New Mexico's arena seen from the upper seats in March 2011, with the crowd stacked steeply down toward the floor. Opened in 1966, it was built by putting up the roof first and then digging the bowl out underneath, so the playing floor sits 37 feet below street level and the sound has nowhere to go. It hosted the 1983 Final Four, the tournament NC State won with one of March's most famous upsets.
