Hi Ralph, Rob and List,

I'm very impressed, and a little paranoid <g>.
That is a great piece of software you have there, Ralph
and yes, you are right on target - surprised it
doesn't show my house!  ;-)

I live almost exactly 4 miles either way of Smoaks and
Lodge on Highway 217, which is almost due east from
point to point.  I know it was a bit of overkill,
but I'm an obsessive, perfectionist type and when I
determined the coordinates of Smoaks and  Lodge, which
were given to 5 decimal places, I interpolated my coordinates
from those given and just kept the resolution at that value.
I also zoomed in on the map until I could use landmarks on the map (e.g.,
roads, intersections, creeks, ponds, county borders, etc.) marked the
location where my house is located, reloaded the map with the new location
and then was given the new coordinates to 7 decimal places.

I realize it's not needed for normal astronomical use or satellite
observing, but I just like it - especially when I go back to Tiger Mapping
Service of the U.S. Census Bureau and plug these numbers in and can 
see the intersection of roads and the creek that flows behind my house!
Like Rob said within 2 in. - I guess it would be of great use if the Air Force
wanted to bomb fire ant hills in my backyard! <g>
Anyway, I just left the values at that resolution for the heck of it.

Ralph, what software did you use?  I'm impressed it has such arcane info
like Little Swamp ( I mean I'm in the boonies)!  Did it by any chance 
mention Padgetts?  That is where I actually live - a little rural community
of around a dozen folks!  The Census Bureau doesn't even give details like
that on their map server!

BTW, I did make a slight modification to my coords., the ones I were using
were the ones I interpolated, but after you and Rob made comments, I went 
back spent a little time and revised the coords to get even closer to my 
backdoor! <g>  I made a change of a couple hundred feet or so.
I was still on my property though!  ;-)
This was all just a fun exercise, I didn't really expect anyone to point it
out, but I'm beginning to realize the keen observational skills members 
of this list possess, such as Rob and yourself!
I guess that's what observing satellites will do for you.  <g>

P.S. Ralph, where did your daughter visit in SC, perhaps, Myrtle Beach?
