I was at Rams vs Huskies test event at NMS yesterday, and the stadium is amazing. We sat in a few sections and there aren't really any bad seats, even in the end zones.
And man, New Mosaic is going to be LOUD thanks to the canopy. It was really loud yesterday, even though there were only 16500 people, and the crowd seemed to be split evenly 3 ways between Rams fans, Huskies fans, and people who didn't care about either team. Once the place is packed with 33,000 Rider fans it'll be deafening
