(a little back story) I started skiing at age 3 in the 70/71 season, loved it as a kid and teenager. Marriage and money (mostly money) caused me to stop in the early 90's. I got back into skiing in the 08/09 season, my kids (now son 21 & daughter 18) skied for the first time in 09.
3-4 years ago, my son and I got fat powder skis and we absolutely LOVE the pow and out of bounds/off piste. I got my daughter a pair of powder skis a couple years ago, but she had never really taken to it like my son and I.
Last Saturday, we went up to our local mountain (White Pass). It snowed about 10 inches throughout the day. The powder was light (for the PNW anyway). We enjoyed 4-8 inches of powder most of the day and she was having fun (even with the windy conditions). The last run of the day, I gave my daughter the option of following my son and I off the main run, and she said she wanted to. Virtually no one had been in this area, 6-12 inches of light powder, we ran it for over a half mile. About half way down, after a particularly nice patch, I stopped to wait for my daughter. She skied up to me with an ear to ear grin she couldn't get rid of and giddily said "that was the BEST!", she was just glowing with enjoyment. What I had been hoping for for years, had finally happened, she had that "powder moment" and fell in love with it. She couldn't stop talking about how fun and cool it was. I told her she couldn't imagine how happy that made me to hear her say that.
It turned out to be one of my (our) most memorable days skiing ever.
