Some of the ideas they had were quite powerful, but they were derived from urban planning ideas from Europe and the Enlightenment. One of the problems was overlaying Baroque systems over more pedestrian grid networks, and using certain land speculation plans that came out of Holland and England. One of the interesting things in the plan was they ended up with a city with more land in open space and rights of way than any other city, maybe, in the world, certainly in America, and a lot of complicated intersections. I was interested in the urban plan, I became interested in how it ended up wanting to be like the great European cities, especially Paris, but ended up not being like them at all, and then the problems it had. I became interested in all the designers who'd worked here, and most of our great designers, certainly some of the great landscape architects, Downing, Olmsted, Peets, Eliot, Kiley, all worked here
