Lifelong Texas High fan here. (Also with a cousin who is a PNG grad). TH fan base is strong, but admittedly is no match for the PNG fanbase that is legendary in Texas high school football. There are 3 high schools on the Texas side of town. All 3 are still alive in the playoffs. Liberty-Eylau (3A) and Pleasant Grove (4A) play on Friday afternoon, so there will not be any opportunity for the fan bases to join forces to support a Texarkana team. PNG fans will outnumber Texas High fans by a substantial margin.
Responding to a couple of comments on this thread. First, regarding the Texas High-Arkansas High game. It was discontinued primarily due to the fact that it was no longer competitive. Arkansas High has fallen on hard times and is much smaller than it was. It does neither side any good to have a rivalry game 50-0 at halftime. That leads to fights motivated by frustration. Safe call was to just not play the game anymore. Really sad. It also means that Texas High loses a local game and has to replace it with a long road trip to DFW or northwest Arkansas.
Grim Stadium. Yes seating is approximately 7500. The band and students do not sit on the "home" side. They take up approximately 40% of the visitors side, leaving the entire west stands for Tiger fans. Still one of the best places in the state to watch a game. No track. Minimal distance from concrete stands to the sideline. Concrete stands rise at steep angle to create a "cavern" effect. Horrible for band, drill team and cheerleaders. Great for fans watching a football game. Low in the stands you hear every conversation between coaches and officials and players.
Great old story about Earl Campbell being asked about the hardest hit he ever took playing football. His answer: The concrete wall at Grim Stadium in Texarkana.
