Most teams don't play home and away games at the same stadium. During the away game at Albilene High, when it shows the scoreboard it says Albilene School District. The next game against Cooper, the scoreboard still says Albilene School District.
The Abilene school district has 3 schools -- Abilene High, Cooper, and Wylie. All 3 schools use the same field for their games; therefore, Abilene High and Cooper would play at the Abilene ISD field.
Actually, Abilene-Wylie does not use that stadium, except for rare play off appearances. The stadium is Shotwell stadium and AHS and Cooper both play there.
