Sacred tract. No Trespassing -- a sign posted beside the road. Slow down. Unicorn crossing -- a further sign. We obey, decreasing sullen throughway miles of speed. Sacred tract? No trespassing? Looking to right and left, guessing at pearl spiral, at marble stud, we slow down for the possible crossing myth. We hold back, back from closing in, having reached a likelihood of sacred tract. No trespassing is our intent. No craving, no chasing the visionary ivory steed. Slowed down, we behold a tossing storm of mane! Oh grant an easing gust of withers! Cool our need with sacred trace of slow passing snow-cloud: a unicorn crossing!
