[amsat-bb] Proximity to grid line boundary

[tjschuessler at verizon.net]

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.
