I had my 5D with the 70-200 f/2.8 IS lens mounted on a monopod as I came across a trail running alongside the little local airfield, serving small planes, near Fort Vancouver in Vancouver, WA.

I'm still learning panning techniques, which really add the moving dynamic to this kind of shot, so among these you will see a few soft ones, but enough sharp shots to make me feel gratified, and plan to return soon with my 1D Mk III!
