Years ago, when I became the youth director at Camp Yorktown Bay, in Arkansas, I was interested in finding out how much property belonged to the camp. We had a map, and it was easy to find the lakeshore boundary on two sides of the property. But the perimeter lines headed up into the steep oak forest. When my father came to visit, we decided to place markers in the corners of the property. He had been a state surveyor in California, and we had a compass, and a plot map of the land. We measured up the hills, and across the ravines until we reached what we thought was the corner of the property. But as we looked around all we could see was oak trees and leaves all over the ground.
