About 2 years ago.
Christmas 2000, we went to visit my dad for about a week.
This last time we were there, the temperature was a much more reasonable 30 degrees or thereabouts. The windchill was still something vicious, but it was much more tolerable than last time.
It could just be me, though...
Any deity worthy of a graven image can cobble up a working universe complete with fake fossils in under a week - hey, if you're not omnipotent, there's no real point in being a god. But to start with a big ball of elementary particles and end up with the duckbill platypus without constant twiddling requires a degree of subtlety and the ability to Think Things Through: exactly the qualities I'm looking for when I'm shopping for a Supreme Being.
