I was on honeymoon in HI a few weeks back (09/2006). While walking along the shore, I slipped on some algae/seaweed covered rocks and fell. My arm (holding the camera) bore the brunt of the fall, but the right hand (holding the camera) hit a shallow tidal puddle. Only a bit of the camera got wet in the ocean salt water. Mostly on the rear, near the battery cover (the water didn't even reach the bottom of the LCD on the rear of the body). This killed the camera immediately. I took it back to my hotel and let it dry out (a huge mistake). It never worked again. When I got home, I sent it to Canon to see if they could repair it. They totaled it and sent it back un-repaired. When I received it, I decided it would be cool to take it apart and document what I found.

Luckily, the camera was insured, so I upgraded to a 30D when I returned home. I used the new 30D to take the photos of the dead 20D.
