In this part of Texas, the rolling hills and ridges create optical illusions. Distance and altitude of an object are constantly playing tricks with the eyes. From this point of view, the house is high on the hill. The closer I get to the house, it appears lower to the foot of the hill. Just a few yards from this spot, the house appears to be higher. Even with these illusions, I have no problems with compass bearings in this area. Never a dull visual moment around here.
