OKLAHOMA CITY (KOKH) — It's a rust-colored waterway made famous by cattle drives and football rivalries. John Wayne even crossed the infamous river in his 1948 film "Red River". The Red River, however, is known by most in Oklahoma as the boundary between Oklahoma and its biggest rival, Texas. Now, that boundary is being disputed. At least, a small section of it is, anyhow. It's a wild tale ripped straight from a novel that includes lost historical documents and an invasive species.
