I'm leaving to go ski. I think that makes me the winner.

At least in the greater picture.

that is so unfair - why do you get to ski weekdays, eh?

I cover the Saturday this week, so I'm off Friday. Then I took half a day today because it's race night.

Gave myself a little mini vacation.

Do you know that it is not possible to provide a continuous torque from the femur to affect the ski? By Newtons third law if you twist the skis you twist the upper body the other way.
Most people who think they are steering by twisting the femurs are not, at least not in the way they think. You can get some temporary change of the force but that is by twisting the upper body the other way. I'd rather call that countering.

You could argue that a carved turn is when the platform angle is larger than 90 degrees. I'd rather call this an edge locked carve. However, not even this definition would be strict because in reality you have torsion along the ski so that tip and tail has a smaller platform angle. There is no finite point where the whole ski becomes carved. What is carving then?
Further in reality the platform angle changes rapidly all the time due to terrain.

I used to have the opinion that a carved turn needed to be edge locked, but due to the above and after reading BTSs motivations in another thread (a long time ago) I changed my mind. I agree with the definition that FOM and BTS have in this thread. It is much more useful.

I don't put much thought into how the skies are turned, just what they are doing on the snow surface. Newtons third law doesnt quite say you have tp twist to countetact another twist though. Movement=\=force.
In the end its best to just not over think it and ski, and if that doesn't work drink beer.

Night skiing is the key to midweek happiness!

Hey, I just found a pic of me skiing.

I don't have many since I usually ski alone.

It could be that I'm getting ready to lift my inside ski.

Good news is that my butt is healed enough to ski tomorrow.

Better news is some fresh stuff tonight and some inches over the weekend.

Looks like an FX kind of day coming up.
