Check out our documentation of the UGA takeover of South Bend, Indiana. Here is how a Notre Dame site described the scene:
Walking around Notre Dame’s campus all day the red was unavoidable but it didn’t seem that bad. Then we walked into the stadium. When we emerged through the walkway leading to our section the red hit you in the face immediately. Red as a color stands out in general, but this was bad. This was worse than 2000 Nebraska. This was a takeover.
