In the mid 90s I had a couple of close encounters. Hit a small bird whilst I was going a bit quick (no idea what species), the impact on my shoulder took my hand off the bar and left a good bruise through a leather jacket.
The scariest was riding back to med school across Salisbury plain at night. A badger ran under my front wheel, causing my ZZR600 to take off. The impact ripped the belly pan off and on landing and I went into a bit of a tank slapper. Still have no idea how I stayed on, but pulled over at a village pub that was still open to stop shaking and borrow tools to get the flapping bits of fairing off.
Luckily not had anything since!
