The Glass Bowl is the second oldest stadium in the Mid-American Conference, behind Ohio University's Peden Stadium. Over the years there have been many renovations made to the Glass Bowl, such as switching from grass to Astroturf in October 1974; building an electronic scoreboard in 1975; adding seats in 1972; again adding seats, a press tower, luxury boxes, and Larimer Athletic Complex in 1990, and switching to NeXturf, an artificial surface carefully modeled after natural grass, in July 2001. The outer wall and Blockhouses are all that remain of the original Glass Bowl Stadium.
