Chandler lives on Thorn St in Oklahoma, Westmoreland County, PA.  Gladys lives on Grant Lane in North Belle Vernon, also in Westmoreland.  Every year the two friends travel an hour or two to engage in a favorite pastime which taxes their discipline, draws upon knowledge accumulated over decades of study, and requires their utmost attention.  This year they parked in an area surrounded by woods teeming with white blossoms, chose a trail at a bearing of 30°, and, at the end of their time together, exchanged scraps of paper on which was written the following:
