> If you guys will remember from a year ago, Don is the man who pinpoints these sources, if given a few more, reliable, data points.  What is needed are reports from directional loops.  2-3 feet in diameter are fine for getting a sharp null, of a few degrees.  This is much, much better data than from Beverages, etc.
