Amazing ride this morning.
Chatted with another commuter going my way, also riding fixed, this never happens.
Felt something hit the side of my head while riding followed by a squirmy feeling. Turns out, I had run into a bee and it was hanging out inside the vent in my helmet. I stopped and shook the little stowaway out and continued on my way.

It's events like these that make bike commuting so exciting.
