	| Thanks for the additional info.  I had never encountered it before, but it seems to be (or have been) a pretty common (even standard?) method with systematic sampling where within an explicit stratum the frame is usually sorted geographically.  Doing a search, there might be further description of it in Kish's Survey Sampling which I don't have.  Anyway, thanks for the tip and docs.
