Thanks go out to Raffi Derharian for providing me with information to post here from the information sessions held while I was out of town. This post is mostly his words, with a bit of formatting and some other bits (like comparisons to some of the Transit City presentations).
At some point, hopefully soon, there will be soft copies of the presentation material. I will update this post to add links when they become available. In the meantime, Raffi has been kind enough to provide a couple of photos of the drawings. Click on the thumbnails to see them in greater detail.
