Nikon N90
18-55
55-200 VR w/ hood
(Yes the two are DX glass, carryovers from my D40, but I can't afford new glass at the moment and I rather like their vignetting effects. They also don't vignette at the long end)
Spare film
Lens tissue
Reciprocity chart for Ilford Pan-F, HP5+, and FP4+
Sharpie for making notes on canisters
Spare piece of film (for leader extraction via licking)
Really crappy grad ND filter

All in a small blue lunch cooler.
