BrenR,

The illustration is excellent. I think anyone can understand "slope" by looking at the diagram. Speaking of which, years ago while skiing at Mont Tremblant I once took a wrong turn and ended up on an expert run that looked like "C". Took me an hour to make it to the bottom. "A" is more my speed. . .
