Hi Doug!

I trust the latitude/longitude readings from my GPS receiver
(or GPS in phones or radios), but do not rely on those for
county, state/province, or international boundaries. For these
boundaries, I rely on markers/signs. For example, the boundary
between the states of Arizona and Utah was supposed to follow
37 degres North exactly - but it was surveyed long before we
had GPS. At some points, that boundary is just north of 37
degrees North (DMx6/DMx7 grid boundary). Near Lake Powell, the
grid boundary falls in Arizona. Along US-160 or US-191 further
east, the grid boundary falls in Utah. This is even more
pronounced along portions of the USA/Canada border, especially
the section that is supposed to follow 49 degrees North from
Washington state to Minnesota's Northwest Angle.

73!
