Flipping hell... Some people have far too much money!
Anyway...when I'm not doing anything too serious, I normally just carry one Minolta 7000 body, a 35-105mm and a 70-210mm.
If I'm doing some serious photography, I will bring a spare Minolta 7000 body just in case, with the 35-105mm on, have the 70-210mm on my main body and a 50mm prime too, as well as a tripod.
When I go digital, I intend to buy a spare camera body.. Of course, I am no professional, but it's just in case. Nothing like a 1DS though! Two 300Ds will do me! Plus theres that Canon film system I'm building up too.
