Henryk,

Nice job with the lesson. For our club, I put together a basic cross-
country course. After reading your post, I am going to rewrite that
part of my lesson because your post makes it easier to understand.

If you feel like sharing course materials on line I can probably host
them on my site.

Cheers,
