"Now, Therefore, I, Lyndon B. Johnson, President of the United States of America, do hereby designate the month of May 1968 as Senior Citizens Month."
"I transmit to the Congress the Sixth Annual Report of the Peace Corps--an idea come of age, no longer a novelty but now a part of American life."
"Might alone cannot bring peace."
"So that proclamation is now in force and the month of May will be set aside to honor our elder citizens and our fathers and our mothers."
