My Contour was very well behaved during yesterday's climbfest. I climbed Jurgens and Luneman Roads in El Dorado County. Both roads meet at the bottom at a creek crossing. From what I've read about this ride, most riders have to take their shoes off and wade across. Since all I wanted to do was climb, not get my feet dirty, I chose to descend Jurgens and Luneman and climb back out.
On the way to the first climb (Jurgens), my Kodak Playsport's tripod hole finally gave up the ghost and the camera flopped out of the mount. It was recording, of course. I chose to have a second camera recording as a back-up in case the Contour failed. It left a good sized chunk of plastic behind in the handlebar mount.

What the Playsport's tripod hole looks like now. Needless to say, this camera definitely isn't waterproof any more.
