But for my last 37 Christmas's they have been blue sky's warm weather, family and friends, playing outdoor games, like cricket, lawn bowls etc. Having way too much food and drink, and jumping in the pool to cool down.

I would like to experence snow at Christmas sometime....for a change.
Wanna trade houses for the next couple weeks to months?

no kidding, the best part is scraping an inch of solid ice off your windshield & go to open your car door... only to find it frozen shut! ice is great for some things, but i am growing to hate it! :lol:

If anyone is interested in an easier way to convert between F and C than I have ever seen in any textbook, here it is. We start with a few basic facts: 1) water boils at 212°F or 100°C, 2) water freezes at 32°F or 0°C, 3) the one point where the two scales are equal is at 40 degrees below zero, -40°F = -40°C.
Therefore, the freezing-to-boiling span is 180F° (212-32=180), and 100C° (100-0=100), or 180F° = 100C°, 18F° = 10C°, and 9F° = 5C°. So to convert any known span of degrees from F to C, divide by 9 and multiply by 5 (multiply by 5/9); from C to F, divide by 5 and multiply by 9. (Does this sound familiar?). The hard part is that pesky 32°. Add, subtract, before dividing, after dividing???? IGNORE IT!!!! Instead, make the first step of converting in either direction adding 40 to your starting number. What this does is give you the number of degrees to that equivalence point of -40. Then do the division and multiplication, subtract the 40 again, and you are done! You do not have to worry about the difference in the baseline because you are using a new baseline, where F and C are equal.
Try it, it works. 212+40=252÷9=28*5=140-40=100; 100+40=140÷5=28*9=252-40=212;
32+40=72÷9=8*5=40-40=0; 0+40=40÷5=8*9=72-40=32; 98.6+40=138.6÷9=15.4*5=77.0-40=37 (average human body temperature); 70+40=110÷9=12.2*5=61-40=21 (Christmas day in California and maybe Christmas evening in Australia after the 30° day?)
I assume that for temperatures below minus 40, one would subtract first and add it back after converting, but I have not tried that, and since I have no plans for visiting Antarctica, am not worried about it.

+1 Very cool.

So, how did we like the Indoor S'mores?

well, i'm a tad bit disappointed; we had about half an inch (3cm) of snow last night, and it's pretty much all melted off already. supposed to rain and be in the 40's (F) all the way thru christmas. i was kind of looking forward to snow, it being my first time back in the area i grew up in, for many years.
however, it's also the first time i'll get to see my 1yr old twin nephews enjoy christmas, so i won't be wasting much time caring about the weather, at that.
