I saw a fishing show where they got Alligator Gar in the Trinity. They were freakin huge, I mean hundred pound class fish. Towed the stinking boat around. The water looked like coffee with cream. About as clear as a brick.
Looked like more fun than should be legal.
I just looked in the IGFA record book and there is a record from the Trinity also. Plus all of the fly rod records for them are small. 30 pound and less small.
