Crank bolts coming loose are interesting. Can never forget the look on the mechanics face when I cycled into Cycle Surgery at King X with one crank separate from the bike and dangling from my cleats. Didn't want to put my foot down as to not scratch the crank.
Happened to an ex-colleague of mine setting of from the traffic lights... all of sudden something felt loose, next thing was a 10 mile walk home as he didn't carry a spare crank bolt... (well few of us do...)
