Take the spurs off everyone's boots before the lesson. And don't forget that in Texas, you get the death penalty for skiing out of control. And tell the women not to stick their poles in their big Texas hair when putting on gloves, it's just tacky.
I took a practice run on the machine today. Not the best thing in the world, but at least you're skiing.
The skis used for training are really small kids skis, with the edges detuned and rounded off so the carpet doesn't get ripped up. About the only thing you can do on the machine is straight down and snowplowing. No carving can be accomplished without falling, since the skis have no edges.
