Not exactly a trip to the petroglyphs, but this photoset was from a day of surfing at Olowalu Beach, across the highway from the trail to the petroglyphs. Unlike my landlocked brethren in AZ, I grew up surfing at Malibu and Ventura. The surf was pretty small, but a bad day of surfing beats a good day of work anytime.
After this trip I learned that there had been 5 shark attacks at this beach and one was fatal. Ignorance is bliss.
