Ah. A new skill I have to master. <g>

I like it! Where does one find the process described? Or does one ask
His Mooseness to describe it? The more I do the more I realize I don't
know.

Casco Bay. A bit south and west of here. Round Pond is on Muscongus

woods. Some bodacious osprey nests. Haven't been down there in a while.

LCE I've got. Curves I'm learning, especially since CS3 and 4 give us
those convenient sliders, obviating the need to actually drag the line
on the graph, which frustrated me no end. <g>
