I’ve been to 13 bills games since 2000. I’ve gone to both preseason and regular season and have sat everywhere in the 100s. Depending on whether it’s preseason or regular season, how close to the field you are or what era of the pre drought, drought or post drought you’re in, I’ve had a split mix of standing and sitting.
I did go to a 1 away game in Cleveland and they all sat. This was the 2013 Monday (or Thursday?) night game
