Allen's new football stadium

A couple of things I learned reading about Allen High School's new football stadium (arttist rendering is picurred here) now under construction and expected to open next year:

• The stadium will seat only 18,000. For some reason, I thought it would be about twice that.
• There are three larger high school football stadiums in the state, Alamo Stadium in San Antonio (23,000), Mesquite Memorial Stadium (20,000) and Farrington Field in Fort Worth (18,500).
• In terms of enrollment, Allen High School is the third largest in the state. The first two are in the same football district as Allen, Plano and Plano East high schools.
• At least twice, the Allen School Independent School District considered closing because of lack of students.
• In 1960, Allen High School's graduating class contained 18 students.
• 400 persons entered a lottery in hopes to being able to purchase the 70 available season tickets to Allen High School  that went on sale at the beginning of last season.
