Stopping in Sasebo, Japan, on the way west, my son took a bus to Nagasaki. Good place for a history major!
I will simply post his comments with this photo.
"oday's pic is of the Hypocenter at Nagasaki. The atomic bomb burst
about 500 meters above this spot. Just thinking about it gave me the
willies. What's more, the little park area surrounding this is built
entirely on a mound of rubble from the blast; it's not uncommon to find
shards of ceramic teacups, bits of metal, and pieces of roofing shingles
that have eroded out of the mound. Very creepy, and a good reminder of
why we never want to see another nuclear attack.
