My Motif fu isn't good enough to provide a maps-browser style interface,
but I can follow this scheme for now by making this code (which for the
moment is US-specific anyhow) try that scheme at least for US.geocode and
then US/SN.geocode for the state; county would involve having a top level
database of counties, fairly easily. I think I will do that after dinner.
