Don't you know that you shouldn't put all your eggs in one basket?
Sorry, I couldn't resist...
My first day in clipless, I dumped the bike over with a dozen eggs on end in one of the panniers along with the other groceries. No extra padding, went over pretty hard. Up until then I was also very nervous about breaking eggs in my bags and the resulting mess.
No damage whatsoever. Nary a crack. They were in the typical styrofoam container.
The broccoli, on the other hand...roadkill.
tsl, love the story about the oranges!
