Point Buchon is PGE property adjoining the south edge of Montana de Oro State Park, a few miles west of San Luis Obispo. The property is open to hikers a few days of each week (daylight hours, only....sniff). The clouds in this shot were from a thick fog bank that stopped right overhead. One second it was sunny, the next second it was foggy, then repeat.
