Here you see photos of "Little Boy." Unfortunately, the bomb pit for "Fat Man" was recently vandalized. While the glass has been replaced, the photos have not, so it looks just like this, except that it is empty.
As you can see from the water droplets on the glass panes, it had been raining that day. In fact, heavy rain moved in immediately after I took this shot. I tried to wait it out, but it was more determined than I was patient. So, I headed back south, to the village of San Jose. We will be back up to the North Field, however, later.
