I have had propane tanks out in -30 F weather. I have never had a problem
with any tanks freezing. 

Are you certain that you had propane and not #2?

True. I had not factored that in. Further, in extreme cold weather,
propane freezes (really, does not go liquid->gas).

Ya, been there, I had to heat the tank VARY carefully with a blow torch.
There is stuff out there to keep the tank heated, but can lead to
problems. 

But barring the gas utility starting rationing, it is in many
places a viable option. I know a large ISP here in DC has such,
or did... 

Ya, also been there. They shut my house off during that winter, but hehe I
own a pipe wrench. So now big deal.
