This goes back to the 90s, before YouTube and all that… My friends and I often roamed the streets of our little town at night, smoking weed out here in rural South Africa, when the light pollution was low and the milky way was very visible and very bright… and in places this small nobody knows the street names, but still know where everything is… so some guys from the city pulled up asking us for directions to a specific street on this specific night… and obviously we had no idea of where to find the specific street… so the guys were shocked, probably reasoning that the place is so small that we should know each and every street’s name, so they asked us “How can you not know where this street is?” and my friend’s girlfriend responded with a SP reference… “We only come out at night.” And so they drove off to search for their destination and we meandered on…
