Lost en route to Albany, GA, vacationing couple Mark and Celia Winocur of Phoenix inadvertently visited the birthplace of former president Jimmy Carter Monday. 'We got off at the wrong exit and were trying to get back on the highway when we started seeing all these signs,' Mark said. 'I figured they led back to I-95, but somehow we wound up right in front of the house where Jimmy Carter was born.'' After buying a road map at Miller's General Store, where the 39th president first learned the value of a dollar as a young boy, the Winocurs were once again on their way to their intended destination.
