I AM SHOPPING in a big pet supermarket, looking at treats and toys, colorful collars, large bags of food, everything a pet owner could possibly need or want. I don’t think my dogs are spoiled or indulged as I draw the line at dressing them up in fussy little outfits, but they eat organic food, are brushed with a goat hair brush, sleep on soft beds. They drink filtered water.

I AM STANDING on a quiet side street in Hiroshima, Japan. A small granite monument indicates what happened right here, 1800 feet above my head. On this very spot, on Monday, August 6, 1945 at 8:15 in the morning, the atomic bomb exploded precisely where I stand, devastating the city of Hiroshima, instantly killing 80,000 people, hundreds of thousands dying later. This plaque marks ground zero, the hypocenter.

I AM PREPARING the cabin for takeoff. Inside the lavatories are cages filled with small, brightly colored parrots. We have received special dispensation from the Federal Aviation Administration in the States to stow these birdcages in the aircraft lavs for takeoff and landing.

I AM WATCHING Day of the Dead festivities in Oaxaca, Mexico. The holiday is in full swing, welcoming the souls of the dead back to the land of the living for one night a year, to celebrate, to commemorate, to honor and remember those who are gone from our sight.

I AM LEARNING about Dia de los Muertos, a lively holiday celebrated over 5 days when the dead are thought to return to visit the living. Here in Oaxaca, Mexico, the city is resplendent with traditional decorations. Special foods are prepared and eaten. Ofrendas, offerings placed on altars, are seen everywhere with photos of the departed, honoring their lives, their favorite food and drink set out to refresh them after their long journey from the underworld.

I AM ADMIRING a henna tattoo I have gotten in Goa, a vibrant, colorful seaside town on the west coast of India. I love my tattoo. It is temporary, inked on my skin with brownish red henna, a semi-permanent vegetable dye. It will last 2 weeks if I take care of it. Don’t get it wet, don’t rub it, treat it gently and enjoy it for a fortnight.

I AM FEELING like an intruder. I came to see a beautiful 400-year-old church in Moldova, somehow built with neither nails nor mortar. The church is stunning, the peaceful grounds neatly groomed. Flowers bloom everywhere. White doves flit around the roof.

I AM PHOTOGRAPHING inhabitants of a dog shelter high on a hill overlooking Dubrovnik, Croatia. The setting is stupendous. I don’t understand why this land hasn’t been appropriated for luxury condos or a beautiful hotel.

I AM DRIVING to the Cape Cross seal colony on the Skeleton Coast in Namibia. This desolate, windswept stretch of sand and driftwood is aptly named. Remains of shipwrecks litter the beach, or sway in the rough surf, too treacherous for a salvage operation, left to slowly rust and rot, waiting to be claimed by the pounding waves.

I AM HEADING to the airport in Oaxaca, Mexico with my taxi driver Oscar, a big burly man who smells of cigarettes and speaks very little English. It is 3 o’clock in the morning.
