My general policy for days like this is to take one camera and one lens. (The only other things in my camera bag are spare flash cards, and a bottle of water.) The D300 is heavy enough without having to schlep all the extra weight of more lenses.
I also have a paranoia that, when transient compositions are forming all round, all the time, the simple act of changing lenses will cause me to miss pictures. The same applies to chimping. I try to avoid looking at the screen on the back of the camera as much as possible - and do so only to check exposures.
I also tried out using auto-ISO, with the camera set on manual shutterspeed and aperture. The reason here was that I wanted to ensure a high enough shutter speed to eliminate most camera shake and subject movement (except - see #3 below), plus sufficient depth of field. In the event, I think it worked pretty well - but it does mean accepting some absurdly high ISOs. Picture #1 below, for instance, was ISO 2200: ridiculous, but I don't think it matters. With the high ISO pictures, I've just done a little chroma noise reduction, and nothing else. (I suppose that, having grown up with Tri-X and HP5, a little electronic "grain" is the least of my worries.)
Of course - a day like this is not worthwhile without sustenance. During the afternoon, I introduced my fellow Wonkies to Maison Bertaud in Greek St, where we restored our blood sugar with cakes and coffee. These are essential during any photo walk!
A few quick edits from the day: I've put some more on Pbase.
