A method of navigation superior to GPS, which utilizes the measurement of relative air-current temperature. The method involves the application of saliva to a male’s scrotum by a female’s tongue. The scrotum is then placed outside the window of a moving vehicle. Air currents are analyzed via temperature changes detected in the epidermal layer of the scrotum. A normal vector corresponding to the isothermal region with the lowest relative scrotal temperature is deemed the “sacknav” vector. The sacknav vector always points parallel to the direction of final destination, via the path of least resistance.
Orion used sacknav to successfully navigate the roads of Vancouver.
In-built biological navigation system used by the male of the species to find a mate. Generally initiated by combining a state of over-laden plums
