They have a 400 head dairy farm in WNY with trucks in and out all day and they gotta keep the roads there spotless
My wife has been laughing at the weather alerts since they were issued. She grew up in snow country in WNY. They average around 125"+ of snow per year. We get 26" over thanksgiving while we were up there they got 18"
He played A LOT of snaps for a big DT like he is. I don't feel like he was injured that often, he did start every game for 2 years and I believed played in every game all 3 years.
