I've read many of your profiles and bio's and it seems to me that there must some relationship between photography and mountain biking. I have some bikes hanging from the ceiling of my garage and I just can't see the connection. It seems to me an awkward and dangerous (and downright silly) way to take pictures! Even with IS lenses!
No, I must say I'd rather take a camera fishing instead. Although I once fell into a river full of 50-degree (fahrenheit to all you metrics) water with my wife's $1,400 Contax point-and-shoot. Things I learned thereafter:
#1 - it wasn't very waterproof
#2 - my wife gets mad when I ruin her camera
#3 - the repair people are pretty smart by charging me $700 to repair it (let's see...lose $700 to repair it or save $700 to buy a new one)
#4 - it's much cheaper to put a camera in a $0.02 sandwich bag before I put it in my fishing vest.
Oh, and yes, I had it repaired. Still works like it's brand new. Anyone want to buy a TVS II in mint condition?
