scroll through the pages with the arrows at the middle edges of the book While at John King yesterday I came across two copies of Detroit: It's Trolleys and Interurbans and was very disappointed by it. It's not a very big book and is saddle-stapled and didn't look any better than the articles that I've seen in journals so I didn't buy it. Which is what inspired me to scan the Detroit in Perspective article from 1973 written by Allan Treppa. Here it is in its entirety. Since I haven't read it yet I won't comment on it.
