"On earth Day, April 22, 1970, early in the morning, I went to the legislature in Albany

with Senate Majority Leader Earl W. Brydges, Senator Bernard C. Smith,

and Assemblyman Glen Harris.  We met more than seven hundred student leaders from throughout

the state, and I signed into law the new Department of Environmental Conservation.  That morning, incidentally,

I proved that I could still ride a bicycle-even though I was so preoccupied with staying on the thing

that I rode the wrong way on a one-way street.  

- Nelson A. Rockefeller, from "Our Environment Can be Saved", Doubleday & Company, Inc., 1970
