Assume I have the latitude and longitude of two points separated by a thousand feet. I want to find the mid point on a straight line between the two, or for that matter, anywhere along the straight line. There are trees between the two points so that they cannot be seen. What is the best way to do this? Is there an easy way to do it with the GPS units?

Stan,

If you are talking about a real world example, you can simply stand at one of the points, and have the GPS point to the other point. Note the bearing and distance to the second point. From there, it's a matter of walking towards the second point until you have
a) reached half the distance noted when you were at point 1, and b) still have the same bearing pointing you to point 2.

Otherwise, you might consider purchasing some mapping software like National Geographic's Topo!. You can plot both points
on a topo map, draw a "route" between them and then have the software place several markers along the route giving coordinates
along the way.
