As soon as I arrived in Arizona for my interview in February I was struck by the green trees I saw as I drove around town. The palo verde is the state tree of Arizona, the green in the bark contains chlorophyll so they can use both bark and leaves for photosynthesis. I came across this one shortly before sunrise when I visited Pinnacle Peak Park in Scottsdale. We have accomplished a lot in the past six weeks but there is still a lot to do, I feel a bit like this tree, sprawling in all directions, a bit worse for the wear, but still standing, still growing.
