Bridges as walls The biographer of Robert Moses, Robert A. Caro, refers to the bridges and underpasses of the famed New York State parkways. These bridges and underpasses are quite low, intentionally specified by Moses to allow only private cars to pass. All those who traveled by bus because they were poor or black or both were barred from the use and enjoyment of the parkland and its "public amenities" by the technical design of the bridges. Even at the time of Robert Moses, a political statement of the form "We don't want them blacks in our parks" would have been unacceptable in New York State. But a technological expression of the same prejudice appeared to be all right. Of course, to the public the intent of the design became evident only after it was executed, and then the bridges were there. Ursula M.

Finished on the inside "Those stretcher bars were finished on the inside in ways no one will ever know; I spent days, weeks, months finishing things no one is ever going to see. But it had much more to do with the fact that I couldn't leave them unfinished. I just had this conviction that in the sense of tactile awareness, if all those things were consistent, then the sum total would be greater, even though that might not be definable in any causal, connected way."
