Lyndon Johnson actually said...

Houston's destiny and America's destiny is greatness, and that greatness will be fulfilled by the faith we place in our responsible vision.

Many factors have contributed to Houston's growth and the growth of our great gulf coast.

On the 50 years past, you have my congratulations; on the 50 years ahead, you have the Nation's confidence.

I wish to be equal to your confidence, and to the hopes of all of the people of America.
