NORTH CAROLINA/SOUTH CAROLINA BORDER -- After a couple of hundred years, the 334-mile long border between North and South Carolina changed Jan. 1.

The states spent two decades using GPS technology to precisely map out the line down to the centimeter.  

The changes only impacted a couple of dozen people. For a half dozen homes along the Gaston/York County line, it now means part or all of their home is now in North Carolina. Most of the residents are elderly, and the change is costly and time-consuming.

"Why move it now. We've lived so many years already with what you did. Why move it now? Why hurt old people," said Marvin Rutan.

On another portion of the line, three North Carolina families were moved into the Palmetto State.  

Both states approved the changes last year.
