Just out of curiosity, how do the rules for states? I tried to activate 3 states from a three-state boundary where there was a marker. (It did not work because of the same problem--trees and grass) but I'm wondering if the marker would be sufficient evidence? Depends who placed it, I suppose?
This was for an informal 'contest' but for something like WAS, I can imagine it would be important.

Which is obviously why it is a lot harder to hit a 4 corners location because it will invariably plop you in a grove of dense vegetation. I will stick with the two grid on the line on a main rod thing because I can get it right.

You should operate at the spot where your GPS receiver (using the settings/rules that Don highlighted) reads out *.000000 for a line or *.000000, *.000000 for a corner.

The VUCC rules ( http://www.arrl.org/files/file/Awards/VUCC%20Rules%20April%202020.pdf) state:
(F) Grid boundary lines and grid corners must be established using a GPS receiver whose map datum is set to WGS84, the global default for curif nt GPS receivers. The GPS receiver should be set to use WAAS (Wide Area Augmentation System) if so equipped, since this improves the error figure to as little as 5 feet. In no case may the GPS receiver show an error figure in excess of 20 feet. Any modern GPS receiver equipped with WAAS will easily meet this requirement, as will most older units without WAAS.

For my information, as I am not much of a rover, but as I may be doing a little local grid rove sometime next weekend by request, how far from a grid boundary can you be for it to count? I found a 4 corners grid boundary in my area, but it is way rural in a deep clump of vegetation with a dirt road a couple hundred feet away. What is the maximum deviation from an X .000000; Y.000000 location for it to be legal as a 4 grid location? I will probably do a much easier 2 grid line location, but just wondering.
Thanks much.
