Grapevine-Colleyville ISD has initiated two changes for those attending football games at Mustang-Panther Stadium this school year.

The new safety and security protocols affect entry and postgame celebrations, according to district officials.

Fans are asked to use clear plastic, vinyl or PVC bags that do not exceed 12 inches by 6 inches by 12 inches or one-gallon clear plastic freezer bags with items needed during the game.

It is a similar process used at professional or collegiate sporting events. The Grapevine High School and Colleyville Heritage High School booster clubs will have branded clear bags available for purchase.

There are exceptions made for medically necessary items after an inspection. Student participants may use team-issued bags but must enter through the media/field entrances.

Prohibited items include but are not limited to purses larger than a clutch bag, coolers, briefcases, backpacks, fanny packs, cinch bags, luggage, seat cushions, computer bags, camera bags, binocular cases or any bag larger than the permissible size.

Following events, the postgame celebration has been moved from the field to the north end of the stadium by the field house and track. Fans should exit the stadium and enter the field house/track area by the north field gate to celebrate with the players. Only credentialed personnel will be allowed access to the field.

This change was made for crowd control and safety purposes, according to school officials.

Grapevine had its first home game Sept. 1, with additional home games scheduled on Sept. 9 and 23, and Oct. 14 and 28. Heritage will play its first home game at the stadium on Sept. 30 against Grapevine. Additional games for the Panthers are Oct. 7 and 21, and Nov. 4.
