While I'm not in that immediate vicinity, Bowling Green VA would be
within a reasonable margin of error for the bearings I got on 1610, and
would seem to be within a margin of error for some of the others
reported. I tend to agree that the greater the distance the greater the
magnitude for potential error, and for the majority of those reporting,
one would have to ascribe a nominal +/- 5 or even +/- 7.5 simply due to
the imprecise nature of a portable radio or even a loop bearing. A loop
outdoors in a field would likely be more accurate than a loop indoors
which would be affected by metal within the building structure. 

Unfortunately, applying that kind of a range of potential error to the
bearings posted would cover the entire area of SE VA.
