Damn, you’re really on a roll this morning! Did I ever mention that I almost majored in Geology at Penn State? That was before I faced up to the fact that it wasn’t all poetry; I would have to take a lot of hard math and science course, and if I survived, would must likely end up working for an oil company. But there is at least one blogger who mixes geology and poetry quite comfortably: check out Connaissances if you haven’t already.
A lot of great images in your comments. I can’t shake the feeling that you might have missed your calling as a science fiction writer.
there is constant exchange of territory, back and forth
Yes, that’s exactly what i was getting at in the post, I think.
