>>to correct the "Opacity_map.jpg" link above to read "Opacity_map.zip"<< Got it, Lou, thanks very much and, yes, the trips were restful in an odd sort of way. Traveling is hard and the older I get the more I notice it. I take plenty of time to get where I'm going, but it's the time zone changes that get me the most. I'm up at 3am these days and dead in the water by 5 pm, so it's going to be another week or so before I'm back on schedule. Thanks again Ted
