Has'nt happened in the last 10 or so years here (global warming),
though still gets down to bout -1C, love the fresh mornings.
Back in the early/mid 90's here we used to get such frosty cold nights that you had to get up 1/2 hour earlier to defrost your car as it was encrusted in a 1/4 inch ice cocoon.
Could'nt open the door's, nothin.
No hose outside as all the taps, hose were frozen. cold water in a bucket would'nt do it, used to use a steel spatula at first to scrape the ice from the screen but that was too slow so had to try warm water, took about 3 buckets to defrost the doors and screen and you had to actually dry the screen as, if you left it wet it would freeze up again when you were driving.
In the early days before we had to cover them up you would get up in the morning and go to fill kettle or have a shower and FUCK no water coming out the tap, meter was frozen,
so had to fill up kettle night before so u could use it to defrost the meter in the morning,
got sick of that and eventully made a cover for the meter.
Though the one's that were new to the area with no covers, their meters would freeze so bad that it would crack the meter open and at about 11 oclock they would be defrosting and they'd come home to a water fountain.
Also i remember at that time I was working at the Seymour hosp redevelopment, the job was at framing stage and the slab, puddles, pine framing, everything was frozen solid you coud'nt touch anything and had to wait till about smoko when the rising sun warmed things up.
Yep, love the old Vic.
