Nothing particularly interesting I suppose, but Nebraska uses field turf as its playing surface. It has since 1999. They are putting a new field turf in and doing it in two tones of green. It is supposed to be evocative of the way they used to have the field look in the 60s and so, before they went to astro-turf. The fans seem quite divided on the issue as you can read in the comments (more pictures, as well).
