Not too far from the capitol in DC is the sprawling expanse of Arlington Cemetery. It is a very somber place... It was just my son and I, walking around for quite a while together. I think it all made an impression on him. We stayed so long into the evening -- we were the last ones there! Except for the security guards, who walked with us as we were leaving, since they locked up behind us. It was nice, however -- they took their time and let me set up for a few final shots with the tripod as the light was falling behind the storm clouds.
