Many years ago, back when I still bow hunted no matter the conditions, it was opening weekend of bow season, and very warm. Just before dark on the opening evening hunt, I thought I would get down from my stand and still hunt up to my first attempt at a food plot. And sure enough, a beautiful 90-100 class 8 point 2 1/2 year-old buck was feeding in my clover. So I belly-crawled through the waist high grass along the edge of the plot to get a better look. I laid in the grass until well after full dark.
That was long before permethrin had been invented, and when DEET smelled so strong no one used it hunting.
My chigger count? 100+
I'll never forget the agony of the next couple of weeks.
