I’ve done a lot of sketches of logging equipment over the years. Here’s a partially loaded logging forwarder from around that same time. Again, the front tires were a chore. If they were straight on at a 90 degree angle to me they would be no problem, but the perspective of a round tire at an angle is really difficult for me.
The perspective of straight lines is a lot easier. One day I was waiting for somebody or something at the Fisher Museum at the Harvard Forest. The walls of the small museum are lined with a fantastic series of dioramas depicting the evolution of the central New England forest. I captured this view of them in about a half hour.
