Lee, this is a very informative post. I usually hang around down in the political forum, but a friend of mine called me yesterday and told me about what you had written.

I teach a course on using a GPS with map and compass. Everything you say rings true.

I have found that it just " clicks" in folks minds when they see it first hand for the first time...But as often as not there is alot of confusion right up to the point untill they " see" it all work out on paper.

Consider this an invitation to come up to Hot Springs to compare notes.[8D]
