Winter Snorkeling In Southern BC

It's still five days before my first radiation appointment. My husband and I decided to stay in the Okanagan at my Uncle's place instead of driving the return 22hours back to Houston with the roads the way they can be at this time of year.
I have returned to what I'd guess was 85% "me". A heat flashing, sore and skeptical "me," but still myself all the same. Back to swimming and jogging on alternate days and yesterday ripping up the powdery slopes on Big White mountain with our daughter Lindsay. It was ski demo days and I ran a pair of Lady Salomons and then Infinite Nordicas through the trees. I rode them hard and came up smiling. Wow. Like having rockets attached to your feet.They both seemed easier to steer around trees and moguls and I have to admit this would be the year to give myself a break. My Fischer AMC's are giving me some cosmetic grief with the top layer of vinyl lifting up. So far it hasn't caught on any stumps, causing a wipe out, but it does affect over-all confidence which you need when heading off to the true steep and deep of places like Revelstoke, like we are in about three hours from now.
We found a three day "stay and ski" deal on-line through the Sandman and the weather forecast says snow, snow and more snow over that time period. We get a kitchenette so we can do our own oatmeal, yogurt, seeds and blueberry breakfast. Lunch on the slopes and dinners at one of the many great restaurants we remember from all our Cat Powder adventures there. It's been four years since we've skied this place and now they have the new Longest Chair Lift in North America on their slopes, which will deliver us back up to the sweetness of the powder bowls above. My snorkel is packed.
We will be coming back to Kelowna after that for two days of mandatory "rest" before the first zap of the radiation machine. Poling with my right arm seems to cause a slight swelling of the right breast. If this happens, the measurements and co-ordinates taken and fed to the computer for where to radiate, will be off course and they will need to start again by re-simulating and then waiting another 9 days to start treatment.
Okay, so now you're shaking your head and asking why I am tempting fate like this. Don't I want to get this over with? Aren't I scared of causing a set back?
In my defense, I can only say that powder skiing is one of the softest poling sports - you plant in virtual air. I am careful not to use the right arm to push myself when traversing or walking uphills. My left arm is strong enough to over-compensate. Add to that my determination and downright donkey-ness to continue doing what I place above almost everything else in my life- skiing, and you have my reasons.
And..I should add, there are these wonderful things called ice packs and anti-inflammatory drugs.
Have snorkel...will travel! Full-steam ahead.
