Man, I feel for her, I'm a grown man, and my 10 year old daughter and I have been skiing twice. I noticed that she was better than me the first time simply because of the pinewood derby car effect - heavier things go downhill fast ( No I am not a tubbalard - not superfit but I do weigh more than the average 10 year old ).
We watched the other skiiers first time, and learned tilting skis inward toward each other and turning. My daughter was even able to ski a blue trail at that first smaller ski area. I was able to ski all the green trails as was she.
The next place we went, though we were both turning and not falling on the bunny slopes, but we tried a green (labeled easier) trail, and it was just too steep. At that place we were confined to the bunny trails the whole day.,
Myself, I had to ski sideways across the green trail and stop, then turn around using the poles and ski sideways again coming to a complete stop all the way down until it merged with the bunny trail. This after we tried to get a lift down and had to wait for the ski patrol to take my daughter down.
Very undignified to be doing this on a trail where 4 and 5 year olds are sking down without problems with their parents.
I find the tilting skis inward to be insufficient to keep me slow enough on the bunny trails whereas this works for little ones. I have to turn aggressively ( it seems to me ) to stay in control on the bunny slopes. I could do this at a faster speed on the green trails, but I would be going too fast to be able to say I was in control (meaning for me, able to stop without falling) I figure if I am forced to accept going faster than a speed at which I am in control to proceed smoothly down the slope, then the slope is too steep for me. I only wish they wouldn't label these slopes green - I figured that meant similar to bunny slope as it did at the first place we skied since the bunny trails are also labled green.
