This is probably not Scott Pruett's wife. But Wedge seems to believe that Judy Pruett does not exist and I figured I could probably prove him wrong. And this photo came up on Yahoo images.
I did learn that Judy and Scott have written numerous books for children. I'm sure 12 Little Race Cars would be a hit here in my house.
Here is a link to an interview with Scott Pruett about writing the books.
I suppose I'll work on finding a correct photo.
[Edit for video proof] Here you go Wedge!
