I went for a swim after lunch and decided to clean the canoe while I was in the water. I kept feeling something move around my feet but wasn't worried about it too much. After 15 minutes or so the canoe was shining, and as I walked out of the water I noticed that my feet looked different. Many small leeches(15-16) and a couple adults had found a couple open sores on my feet to gorge themselves on. What a pleasant surprise! Used a knife to scrap them off. Note to self- don't stand in one place in the water for very long. Lesson learned :)
