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!

How much trust does one have WRT state boundaries and what Maidenhead displays? The borders are often not straight nor do they always align with Lat/Lon ... looking at Wyoming, we seem to have 8 more grids than our rectangular shape would have one believe (some from Colorado and others from Montana).
Anyone else see this or similar?
Thanks and 73,
