Long-Distance Calibration: Calibration is complicated at best. Add problems of long distance, timing and customs regulations, and things get really tricky

Ceuta is one of those odd corners of the globe, a political anomaly cast up after centuries of political storm. Approximately 7-sq.mi. (18 sq km) territory on the north coast of Africa just west of Morocco, it lies about 12 mi (20 km) across the Strait of Gibraltar from Spain. Its strategic location has made it a contested bit of real estate all the way back to the Carthaginians. At various times, it has been under Roman, Byzantine, Moorish, Berber and Portuguese control. Since 1580, it has been claimed by Spain, and is now a Spanish "autonomous city."
