CK. The Third Tree
Niclas Hedell, a listener, poses a problem from his days in the Swedish military: given two trees in the forest, and a rope twice as long as the distance between the trees, how do you find a third tree so that all three make a right triangle.
And we explain how the Stork can catch the Frog.

It should be noted that this solution requires the assumption that the forest has >= 3 trees.
