The photography was pretty good. 950 images; posted 210+ to website. (Satisfactory yield was pretty high -- near 40% -- but didn't post many shots with folks I didn't know.)
Stuck ISO at 800 except for in the best light where I shot 400. This let me work at 1/1250 and F8 +/- ... The cycling photography sweet spot for the 70-200 F4L seems to be F8 -- sharp and reasonable depth for the action. Bicycling seems to require about 1/1250 if you're not panning. I adjusted ISO to be near this sweet spot for action ... crowd/candid stuff generally gets about 1/320 ... higher if I want more bokeh. Got a couple nice race shots at about 1/320 while panning.
Lots of kids racing bikes, a number of good crowd (and friend) shots, and a couple odd dog and bug images. Enjoy.
