I am cutting down some trees on one border of my land. I have the boundary pins located on both ends. The trees lie in the middle and when I am at one end I can't see through the trees to the other end(boundary pin). I have thought about having the wife wear orange vest and stand at one pin or have her shine a flashlight towards the other pin. I don't want to cut down any of the trees on the neighbors property. Is there a way that I can get in the general vicinity and gradually take out enough trees to clearly see the other boundary without enlisting the expense of a surveyor? Google earth perhaps or a portable consumer grade gps?
