The BYU fans were much louder and were grouped together in a couple places, but it was not even close if you took a couple minutes to really compare. Might have been 3 to 1. The blue goggles made the Ute fans wearing white look like Y fans.
Funny thing is a Ute fan I went with said it was 7 to 1 Ute to BYU. So both sides are really biased on a really trivial matter.
