I felt as if I was cooped up inside all morning even though I was walking, or more exactly, pacing the room as a lab invigilator for a test. Then I walked to my car and a couple of times to load a computer system, which I then drove across town to another campus. Then I spent two hours playing with an arc weld simulator. I shouldn't be surprised that there is a simulator to teach people how to weld. There's obviously an app for that. This is just a preamble to remind you that I think we need to get outside and take a photo walk.
