Check out this blood-red field (with white lines and black trim), just like the To Pirates have! This is really quite fucking awesome, if you ask me. Boise State's blue field was the inspiration for the many field colors you find in the GFL (that and how bad-ass it will look if we ever land a video game), but this is the first I've heard of the red of Eastern Washington.
And oddly, I think this report is wrong -- the reason Boise State got the blue field, as I heard, was because their stadium is in a goose migratory route. Geese would stop to land on the green field, and shit all over the place. They put in a blue field because the geese see the big swath of blue, think it's water, and keep on flying.
