Spotted this on the ReunionTalk mailing list (Reunion is the premier Macintosh genealogy software); reposted by permission of the author, Keith Tinkler. Happy hunting! 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. Slán, Mo! (Hanrahan) Langdon
