Digital cameras are great. You can carry them in a pocket and take hundreds of photos, as I do. You don't have to worry about the expense of having the photos developed. Memory sticks hold thousands of photos. Convenient!
I wish I had had one years back, because I wish I had a photo of this:: in the early 1970s, I was out on a snorkeling trip to the Northeast Coast, near 龍洞、佛祖廟. There was no road. To get there, you either took a boat or walked along the narrow, winding path that went up and down and around the seaside rocks. Maybe a good cross-country mountain biker could ride it, but no motorcycle could have made the trip. Very few people went there.
I used to go out on Saturday morning, jumping into the ocean wherever the water looked nice and I thought I could climb back out again. I would spend the night at 龍洞 on a patch of grass just above the surf, hiding from military patrols searching for infiltrators. The next morning I would go to the Buddhist temple for some water and continue walking and diving all the way to 福隆 the railroad station, where I would catch the train back to Taipei.
The Buddhist temple is over two hundred years old. Even in those days, before the road was put in, it was at the edge of the world. It was several hours' walk from the road head. Behind was the land, ahead lay the ocean. Two hundred years ago, it was isolated from the mass of human beings.
Below the temple was a strange geological feature. Open a book flat. See how the pages lie in parallel lines on either side? That is what the rocks were like. I recall that there were only two such formations in the entire world ~~ when the road was opening, some besotted idiot tore them all out to pour cement for illegal 九孔池 abalone pools.行政院長孫運璿親自率領怪手去挖掉九孔池：難怪大家那麼懷念他！The Premier, Sun Yunhsuan, personally oversaw the removal of the cement pools, but the damage had been done.
But the day I am talking about was several years before that. I would wake up at sunrise, go to the temple to beg for some water to drink, and wander through the parallel rows of stone among the tidal pools. I never saw another person down there in all the times I went.
But I did see something that astonished me, and nobody believes me, either. In these tidal pools, one day I saw a frog swimming. I tasted the water. It was salt water. I was wide awake. It was a frog. A frog swimming in salt water.
I watched it for at least ten minutes, to make sure I wasn't making a mistake. I walked several paces back from the ocean, and the water there was still salty. No doubt about it, there was a frog swimming in saltwater.
To this day, nobody believes me, but I swear it is true. Maybe if I had a photograph…
If I had a photograph, some people would say, That doesn't prove it was saltwater, and they still wouldn't believe me. But it's true.
