Yesterday I took my second, third and fourth grade students on a field trip to the Heinz History Center. After our visit, we went on a tour around Pittsburgh in an old WW2 amphibious vehicle that goes into the river and rides around Pittsburgh. It was a cold day, but unusually sunny for Pittsburgh. I managed to get some photos of the city from the river looking onto the point and I was actually taken aback by how lovely my city looked in the sunlight. And it turns out the rivers are green because of healthy plankton, not because of icky pollution. Our rivers actually have bass in them. Amazing!
