track height to my understanding anyway it is according to how far away from the fingers and thumb it is. A high track is very near the fingers and thumb. Medium is little farther down toward the middle of the ball away from the fingers. Low track looks like the ball is almost spinning like a top with the fingers and thumbhole being the top of the top.

I don't really play cards and I am not 79, but it fits together somehow.
It's a 106 miles to Chicago. We've got a full tank of gas, half a pack of cigarettes, it's dark and we're wearing sunglasses.
