alcatraz - "the rock" - is the most famous, and was the most feared, prison ever built. here the inmates were allowed one hour of daily exercise. true, madam. from 1936 until the prison's closing in 1963, there were fourteen attempts but no one's believed to have made it to shore - alive at least. al capone; machine gun kelly; robert stroud, the birdman of alcatraz; all lived in these cells. now ladies and gentlemen, the u.s. park service cordially invites you to become inmates of alcatraz - temporarily of course. don't want to be locked up, fellahs? i don't think so hah hah.
