Classmates of 65ers braved the subzero temperature to reminisce the good old days at the Tai Mo Shan & Kowloon Peak in Hong Kong; and that of the Marmot Basin ski resort in Jasper, Alberta.  [Click here to view the album.] 

Since KC disclosed the secret, I'll send you these photos to reminisce our youthful days; and I could not let KC get away without disclosing his latest Look at Luke, per lmw65wyk.
Thanks Tsai for letting us see what the elusive, unpredictable and "now you see him, now you don't" KC looked like when he materialized at the peak of Mt. Flying Goose at -3 degrees......  Looks cute, almost like a "smurfat" (or whatever they were called, cute shorties living amongst their mushroom houses, always cheerful and mischievous.....).  At that temperature, he should last longer.....!, with less kinetic energy propelling him thrashing around.
Attaching a few photos of my own, taken ~2 weekends ago at the peak of Jasper's Marmot Basin ski resort, about 2,700 m above sea level, at something like -23 degrees C - considered to be "warm" at that altitude, with bright sunshine and little wind. Just the three of us: Sarah, Sigmund and myself.  Derek had to work making sure the planes could fly at the airport; mom did not want to risk slipping on ice; the Doktors had to babysit.
At my age, I'm fully aware of the potential dangers of speed going down at 45 degrees on icy slopes.....   So I go slow, only on beginners' runs; letting the young do their own thing on steeper and higher slopes.  Just plain glad that I am still able to enjoy myself sliding down the long winy mountain slopes; sheer fun!  Hope to do it again, at least one more time before winter's out for the year; may be in March just before my Peru trip.
Keep warm; I heard HK is still getting pretty cold especially at night.   Kids got lost and had to be rescued while doing a winter marathon in the frozen slippery mountain roads or treks in HK....?  Didn't get the details of the news.  I saw some ambulance tires spinning on ice toward the end of the video shot.
KC, you are lucky in HK, didn't have to deal with that deadly snow storm just blew over the Atlantic east coast.  DC was pretty devastated, with 2.5 to 3 ft. of wet snow!  Your apt. should be all right as long you closed all doors and windows when you left!
I am having some headache AND fun at home:  There's a full grown porcupine living in my backyard!!!   Amigo poked his nose into the spiny creature couple of weeks ago and came back in pain, with 6 to 8 sharp "needles" sticking out of his nose.  I had to pull them out one by one with tight gripping forceps!  And the kid never learned, or is a slow learner - he got hit two more times later.  Now I got a metal trap from the Dept. of Fish and Wildlife, but the smart bugger doesn't seem to take the bait so far.  Will see.  Problem is, he is stripping the bark off my apple tree!  Somehow I have to find a way to get rid of the slow moving ball of needles!  Will take pictures if and when I capture the creature.  Someone gave me a recipe for porcupine meat ball...., a Mexican delicacy, so I was told!
Best wishes, Vincent
