To complicate things, the guy who built this house used the "that looks about right" method resulting in the N end of the house being 10 feet farther from the road than the S end. Of course the compass declination is off about -6 deg in the other direction, making my true North seeking Owl about 30 degrees off. The discrepancy is quite visible on Google Earth.

OTOH when I started flying  the declination was +5 deg (give or take)
In the upper peninsula the declination can change 30 deg or more in just a few miles.

There is also 5-10 degrees worth of "slop" in the photography displayed by Google Earth. I discovered this when trying to use the Ruler function in alignment with the walls of my house. :)
