Posterity! You will never know, how much it cost the present Generation, to preserve your Freedom! I hope you will make a good Use of it. If you do not, I shall repent in Heaven, that I ever took half the Pains to preserve it.
John Adams (1735-1826) American lawyer, Founding Father, statesman, US President (1797-1801)
