I do a lot of shops first thing in the morning, and on several ocasions this year I had the water freezing on the pavement.
Easy to deal with though, I had a large storage box [like you can get from Ikea] full of road salt in the back of the van.
I filled it up at the beginning of the winter at one of the many roadside containers that are in every town.
And I was actually chatting to a local copper as I filled it up, he understood totally, its there to be thrown on the roads and pavements anyway....not too sure what his reaction might have been if I had told him I just wanted it for my driveway mind!!
For WFP the big, fur lined, thick rubber gloves that Omnipole supply are top notch, incredibly hard wearing and very warm.
I'm told the Sealskinz are really good too.
The Unger neoprene are fine for trad work, but tend to get shredded quickly because of raising and lowering your pole [no inuendo intended]
I'm lucky in that I can leave a power cable out to the van, so I simply put a small electric fan heater in the back of the van set on the frost stat setting so that it just stops the temperature dropping below freezing.
