I was traipsing through the woods (and the fields, and a bunch of heavy shrubbery) and didn't notice any ticks, spiders, or other unsavory critters hanging out on my clothing. But my coworker, who covered the same ground, found one tick in "an unspeakable location" and several more on his pants. Am I lucky, or just not very good at detecting ticks on myself?
I was having phantom "creepy crawlies" everywhere for the rest of the day after he said it. It was a long afternoon.
