Butterflies and tarantulas. Butterflies besacue they're scary (duh!) and besacue we have swarms of migrating butterflies that come through here that ar creepy to run through. Tarantulas besacue I stepped on a huge one once running my favorite trails. Thank goodness it was already dead, but it was still squishy. I don't dare use the porta-potty on that section of trail for fear one will climb out of it.
