Running in Florida after four late-sumer/early-fall hurricanes, and there was a ton of standing water around for weeks. This led to an explosion of mosquitoes. Was almost back to my car and realized I wasn't going to make it. Pulled off into the woods next to the dirt road and let fly with an anal explosion something fierce. Wiped with some leaves and got on with it.
However, during the two minutes or so I was stopped to do my business, I was bitten 97 times by mosquitoes (I counted when I got home). I felt feverish for a couple hours and itched like crazy for about a week. Worst bite by far was on the tip of my penis.
