Bob- Jim and Fred were probably the most accomplished of the bunch as they traveled some to race. Most of the other ones hung around closer to home but they all had their moments. I wouldn't doubt that entire Family could total 500 checkers so yes indeed, they left their mark.
By the way, one thing I always liked about them was the fact that they didn't block for one another or pile-on during a pit fight or anything like that. In fact, I saw Jim take Floyd out one night for a feature win and then two weeks later, Floyd stuffed Jim into a wall! Good times!
