Where I live (on the ocean) we have a separate saltwater system in addition to city water-I don't like to talk about it much because people become So Upset/Jealous and it hurts their tiny little feelings.
They're all millionaires most of them many times over so there's little reason for anyone else to give a shit-there'll be huge insurance payouts & the smart people will GTHO.
All this drug & alcohol checking is something I've never had anything to do with I guess I just look innocent.
Keep in mind I worked commercially all over BC for decades and was stopped for speeding exactly once and let off with a warning.
