Hey Gary,
Yes, we are very fortunate to have Dave take pictures for us.
That's a clever shot your daughter came up with. Very cool!
Yeah I like to get a telephoto lens also because they only allow the event track photographer to take pictures from the infield and the Turn 5 Cyclone is a long ways from the paddock area.
The pictures Dave took was from my Nikon D80 with a 18-200mm zoom lens and even with full zoom this is the closest he can get.

Here's a 603 x 533 crop area with actual one to one pixel mapping from the original 3872 x 2592 image. Not good enough for printed output but good enough for web page use.
