Gathering every Friday and Saturday night just outside Nob Hill's Huntington Park (across the street from Grace Cathedral), the Vampire Tour is the antidote for those who think the occult can't be fun or irreverent. Tour creator Kitty Burns stars as the 100-plus-year-old Mina Harker. Surely there has never been a more entertaining, comedic version of the legendary vampiress of the dark — certainly not one so friendly with the staff of the Fairmont Hotel (one of the last stops). Elvira should be advised to step aside. Harker is kind enough to refrain from indulging in her nightly feeding ritual until 3 a.m., about five hours after her tour ceases, so birthday party revelers needn't worry they'll become the celebration cake. And fortunately for lazy mortals, vampires don't like to walk too much: This tour isn't strenuous, which we appreciate even though we're not dead yet.
