About a year ago, I (almost?) inducted myself into the photography Darwin Awards as I watched as my 20D/24-105 fly off my truck box @ ~50mph onto the road, resting finally on the middle line. It was inside my dry bag as I was headed out to do some kayaking but not padded or anything. The battery and door blew apart and a small chunk of the battery area went south as well. A small bungee later and some glue and it still works to this day. The lens worked for about another 8 months, suffering only a few missing edge plastic near the main objective. Could you share your close calls or not so close regarding mishaps/bonehead moves and the durability of your equipment so I feel better.
