That's actually a very good point, George, and thasnks for pointing it out! Definitely an error on our part in proofing the magazine because I had and did upload track diagrams for all three layout features, even though the outdoor layout by Fred van der Lubbe is really just two ovals, The other two track diagrams, in their rough-as-submitted-by the authors form, are attached to this post. I will be talking with my designer, proof reader, and kicking myself, for not getting them in. This will be double- and triple-checked in the future.
Top diagram is Mark Watson layout; bottom is Stan Gitler's layout.
