The warm May evening fairly sizzled with bats. Out from under the crannies of Congress Avenue Bridge, Mexican free-tailed bats slipped out in threes, then tens, then hundreds, and flooded the Austin night, sipping from the skies tens of thousands of pounds of insects, as they did every spring and summer night. I felt at once the tickling of wings behind my ears and began shivering uncontrollably. No, fortunately not a bat—just the flick of a stranger’s ponytail at the back of my neck. But the shivery feeling remained; that contact with a stranger was a switch point in my mind. Any kind of creature, wonderful or mundane, slinked in the nooks and crannies of the city celebrated for its weirdness.
