The road to Sept. 11 began here on Highway 15 in Al Baha, Saudi Arabia, which stretches from Mecca into a barren desert landscape and up into the winding, rocky passes of the Asir province bordering Yemen.
Osama bin Laden's father, a Saudi construction magnate, built this highway in the 1960s connecting the kingdom to his ancestral homeland of Yemen, and it was along this same stretch of asphalt that Osama bin Laden recruited 12 of the 15 Saudi youths who were among the 19 hijackers to carry out the attacks of Sept. 11, 2001.
