This is mine. It's absolutely fascinating and so well written. I've only read the first 100 pages, but I'm enjoying the story of the man behind the idea to build the Brooklyn Bridge, and then how the project progressed to completion. It was Roebling's hope that people would come to New York just to see this incredible structure. In the mid-1800's, this would have been the most impressive building project to date. I find I take so much for granted, not knowing what led to such engineering feats that have progressed the country forward!!
