I participated in an organized ride and on the same day at two separate occasions the chain broke on a bike rolling just in front of me. I too have broken a chain while riding and the little chain breaker tool I keep my saddle bag has come in handy. So too if a rear derailleur decides to go kaput while on the ride that tool can make getting home possible under your own steam.

Not sure whether the new chains of today are any better or if its simply that people are now using those speed-linx (or whatever they're called) which lessens those sloppy repinnings, which to my best guess was the cause for this problem.
