Okay, I am going to shoot the races at a local indoor track tomorrow. These are going to be running around an off road track at 30+mph and the like. I am wondering if anyone has some ideas on how to acchive good results with my 20d and 70-200mm F2.8L IS USM. I am thinking AF servo, 1600ISO or so(it is mixed under diffused sunlight and florescent), F2.8 and all the focus points.
Any other advice?
