SALALAH, Oman (AP) — On the eastern edge of the Arabian peninsula, a region disappears under sky-wide blankets of fog as the desert blooms green. This is the Omani monsoon: a phenomenon that draws hundreds of thousands with cooler weather and stunning vistas for three months, beginning this year June 21. A 60-day festival draws about 50,000 people nightly for dagger-dance competitions, musical performances and Sufi exorcisms performed in celebration of Oman's cultural diversity of Arab, African, and Asian roots intertwined by the summer rain clouds.
