My family lived in Cairo, Egypt when I was a boy. It was a terrific experience. During our time there, we visited tombs of pharaohs; saw light shows projected on the temples at Karnak; rode horses around the pyramids; swam in the Mediterranean; and much, much more. One day, I hope to return. In the meantime, however, I'm always on the lookout for new discoveries in that part of the world.

Yesterday, Egyptian authorities approved the underwater exploration of what appears to be a Roman city submerged in the Mediterranean, 20 miles east of the Suez Canal on Egypt's north coast, near Port Said. Egypt's top archaeologist, Zahi Hawass -- recently named one of Time Magazine's People Who Shape Our World -- said that an excavation team had found buildings, ruins of a Roman fortress, ancient coins, bronze vases, and pieces of pottery that date back to the Roman era. Moreover, the team found four bridges that belong to a submerged castle. No doubt, this will be a long, slow excavation process, but I'm anxious to see what else they find.
