The River Walk has a lot of beautiful bridges spanning the river. I first did a quick pen and ink of the Navarro Street Bridge. Then I tried oil crayons and scratchboard for the Commerce St. Bridge, which was just outside our hotel. I can never figure out how to properly use the oil crayons, but the end result was somewhat passable, though the scratchboard is more to my liking. I finished both on the plane ride home.
I tend to doodle when I’m at meetings. I started doing it during college lectures and it’s second nature now. I am actually listening when I do this. I picked up a neat needle-tip gel pen that was perfect for sketching the speakers and attendees at the meeting I was attending. The two large cacti were props on the stage in the main hall.
