A few weeks back I was riding a local trail. My mouth was partially open and something very large smacked my lower lip pretty hard. Fortunately, it bounced off, but it left me thinking about what could've happened. Was it a bumblebee? Dragonfly? Beetle? I don't know, but I'm glad it didn't end up in my mouth. I kept my mouth shut for the remainder of the ride, and pondered how many unfortunate souls weren't as lucky as me.
What's the nastiest, biggest, and/or grossest thing that's ever flown into your mouth on a ride?
