Hi All,
I am shooting (for free, in trade for a booth at the event) an indoor dog event in a couple weeks...basically demos for the public of agility, obedience, "dance", etc.

It's indoors, don't know how dark it will be, or what lighting is going to be there yet.
I'm shooting w/ a D90, have 2 zooms and a 1.8 50mm lens, and an sb600. And tripod. I think I will be able to get quite close to the action. Other than hi ISO, fast lens, etc. any tips? I'm assuming flash is a no no even for just demonstration events.
Thanks!
Rebecca
