Along with 15-20 members of the Chester County Camera Club, my wife & I went on an outing into Philadelphia via the train to view all the Pulitzer Prize Photographs awarded since 1942.

(From online: The Pulitzer Prize for Photography was one of the American Pulitzer Prizes annually awarded for journalism.
It was inaugurated in 1942 and replaced by two photojournalism prizes in 1968: the Pulitzer Prize for Feature Photography and "Pulitzer Prize for Spot News Photography".
The latter was renamed for Pulitzer Prize for Breaking News Photography in 2000.)

This was a heavy exhibit. Many of the photos depicted wars, atrocities, and tragic events of the last 70+ years.
What brought a somberness to me was the realization that I have lived through many of these news events in my lifetime.
I thought, what kind of world have I lived in? Discussing the exhibit afterwards with two photo friends, we felt it would be an important balance to view photos of beautiful things to uplift our spirits and feel, what kind of beautiful world we DO live in!
The photojournalists who captured these moments have recorded modern day history in a compelling and powerful way through their photography.

Photography, of course, was not allowed in the exhibit, but we did have some fun in "Signers' Hall" where 42 bronze statues of the Founding Fathers stand about the room and we were able to "mingle" with them.
