What impresses me, coming from a place that has no vertical dimension to speak of, is how Lake Shore Drive was elevated over all that railroad scenery and now, when you approach that area from the west at the current street level, how far down it all is.
To have at least a mention of railroads in this post, I will mention that I first went to Chicago for a railfan visit from Wichita in the spring of 1970, the same week the CZ came off.
