hey thats cool
for i believe it means we could conceivably hit a 10cm square in september
just like the ones at laorospo & schley taylor
without much more effort than has already been made by you
& we could then at least compare this with the marker that is already there
m
also perhaps someone with the right equipment & ability might be inspired
to return after the harvest to check & retry it from the nearest survey
point or points
but i confess i have no idea what that would involve
>
>>but still
>>since you also seem to be indicating that there are no intervisible
>>monuments available for chalk stringing or cross eyeballing the point
>>i would like to lay a very expensive gps receiver on that stake
>>& compare its experimentally determined position to your legally fixed
>>coords
>>down to what was it hundredths or thousandths of a second
>>which frankly i missed the last time you gave them
>>because i didnt think they would be as necessary as i now realize they are
>>so perhaps you or someone can come up with them again
