A footnote: I think in my last paper draft I overemphasized the prospect of a
few systems being left untouched in the mad rush to move along. I'd rather
focus attention on the prospect that aliens did come to our system, but left
in a hurry after using up some resource we don't see around us. They would
have had no particular reason to hide any signs of their presense, but also
would have wanted to recycle any trash they created.
