During a descent this morning, nothing too fast, going maybe 40-45 km/h (~25 mph), some largish flying insect collided with my chin and then bounced off the right side of my chest. Startling, but no biggie. Shortly after, I could hear a buzzing over my left shoulder. It went away after a few seconds, so I didn't worry too much about it, but then it came back, and then whatever it was started stinging. At that point, I uttered an expletive and quickly pulled over, ripped off my backpack, and started whacking and brushing at where the pain was. I never saw what was stinging me, but it was probably a wasp, given that I found 5 distinct puffy marks on my shoulder and back. Was it the same insect that whacked me on the chin? Dunno.
I also had to brake to avoid a right hook later in the ride. Not my favourite commute of the year, but still glad I rode.
Have a great weekend, everyone!
