This is Allen High School in Allen, Texas, just 25 miles outside of Dallas. Over 1,772 students were in the graduating class. 18,000 people were in attendance inside their football stadium. The graduation lasted almost 4 hours. 🥵 The enrollment at Allen HS is well over 5k students. 😳 Allen, Texas only has one high school. The school is huge. If you were passing it you would think it was a University. Many of the surrounding cities have one or two or more high schools, Allen has remained at one. They are a powerhouse in athletics, especially football. Their graduating class had more people than my entire high school had. 🤯 Have you ever seen a graduating class that big? Have you ever seen a high school football stadium that big? Anyone staying for 4 hours?
