Most survey marks are not of interest to anybody other than surveyors, much less tourists seeking to take them as souvenirs. There are only a few places such as Cameron's Corner, or Four Corners in the US, where theft would be a problem. If anyone wants to steal a National Geodetic Survey marker, the NGS website provides a complete map of them at https://www.ngs.noaa.gov/NGSDataExplorer/ -- Mark _______________________________________________ Tagging mailing list [email protected] https://lists.openstreetmap.org/listinfo/tagging
