Spotted this on the ReunionTalk mailing list (Reunion is the premier
Macintosh genealogy software); reposted by permission of the author,

Just a note to the unwary ---
In North America and Canada there is a slow change over between the
N(orth) A(merican) D(atum) NAD 27 standard to the NAD 83 standard --
MOST maps will still have the older Lat/Long marked around their
margins. GPS systems will usually let you choose either standard
(check the options/preferences/settings area). Check the marginalia
of newer maps to see which standard is used.
