Yes, you do need to say more!
After 5 trips to New Zealand and having been in all sorts of weather and terrain, my cameras have survived. As mentioned repeatedly, I've been under waterfalls and mist and spray and the thing just works even after I've been soaked from head to toe. It has got pretty badly wet but continued to work as intended.
Admittedly, the 5D series are nothing like the 1- series in terms of shock- and weather-proofing, but, they can take quite a battering. I'm not saying I would pour a bucket of water over it or submerge it, as that's asking for trouble!
