oops
this apparently isnt working now
or can you tweak it again so it does
i do have high hopes that there will be some good news
what with all this commotion
but i still dont understand how any of the new info i have seen so
far this morning will actually advance the try
except for correcting your misconceptions of yesterday
which however also didnt advance it
well
realizing that the building line & county line dont match does help
but only in preventing the mistaken presumption that they do
& contacting the owners to get permission would be pointless in
this case because of course they wouldnt want anyone messing
around on their cliff
nor could i penetrate or see the point of arifs or brians new info
either for that matter
so i hope you will correct me if i am missing something
but i do believe you are all beating around the bush
in your most recent additions
whatever is going on atop the cliff might help with the alignment
at the base of the cliff only if one can see & carry the arlington
fairfax county line down the cliff
but this has already been done fairly well by foot & eye
from the pavement change on chain bridge road
& nothing i have seen here yet seems to improve on that at all
maybe something in what you guys are saying or showing can
improve on it somehow
by a hairline
which would be useful
but i still dont see it yet
the fact that you can develop lots of data doesnt necessarily
mean the data will be useful
& i dont mean to prejudge what i havent yet seen
but anyway
we shall see
one more insert below tho

we know fairfax extends into the water for the unknown length of
the tripointing stitch
tho arlington doesnt
dcmdvan is
the fairfax montgomery washington tricounty point too
or us2dcmdvan3famowa in full regalia
the nearby marker wm1 marks us2dcva3arfawa
end inserts
I hope this is a help in finding the tripoint.
