J.T. sort of beat me to it. But ODWC gets no money from the state coffers. It all comes from licenses/fees/etc. They are self sustaining. That's one of the reasons I haven't bought a lifetime yet and probably won't.
They want you to buy a lifetime as not one dollar from the first license has ever been spent. It is invested and long after your dead, you will still be contributing to the wildlife of Okla. The day you die or move away from the state, you no longer contribute.
Its a great deal for the sportsmen and sportswomen of this state.
