Ok... that shifts my property line a total of 27 feet east and 80 feet south of where I thought it was. I now find that the road actully runs through my property rather than in front of it. Then I go in search of the Southeast corner and about the same distance across the road from where I'd marked the Southeast corner before I see a red volcanic rock setting there. Once again I took the GPS and took a reading and that red rock marked the Southeast corner. It was even further off the road though because the road actually runs a little to the west.
Of course this doesn't really effect me because everything here is still well within the property line, but its the fact that the road splits my property that bugs me. I guess I can't complain too much though because the land bordering mine to the north is split in half. 5 acres on one side of the road and 5 acres on the other side. Just makes me wonder about the way the ranch is laid out!
At least now having that straightened out I took the time to find the Northwest corner and will find the Southwest corner tomorrow and mark it.
