Scott Campbell and I both live in Texas, and in an unlikely
physical arrangement. I'm 183km to the north of him and less than 100
meters west of his site. Is there any use for this arrangement for
optical observation?

I know for some types of radio work it'd be useful, as a very large
synthetic aperture, but I don't know an inexpensive way to do that sort
of thing at the moment.
