Which was in response to David Dockstader's question --

And I thought they were talking about the Earth's oceans and fictitious Moon
oceans.=20

Silly me.

I like trees.  There are precious few of them here in my little valley.

just maybe they are dirt tides under discussion.

Again, I am sorry for the confusion.
