Billy Collins: Walking Across the Atlantic

I wait for the holiday crowd to clear the beach
before stepping onto the first wave.

Soon I am walking across the Atlantic
thinking about Spain,
checking for whales, waterspouts.
I feel the water holding up my shifting weight.
Tonight I will sleep on its rocking surface.

But for now I try to imagine what
this must look like to the fish below,
the bottoms of my feet appearing, disappearing.
