Glad to hear that you're O.K. Metal can be replaced..not so much, flesh and bones. I've been around the track many times. In your post, when you said you hit the tire wall, I knew exactly where it was. Coming up the hill on the power every car gets light. Depending on where you are on the track, and how fast you're going, it moves the car slightly to the left. If your wheels are even slightly cocked...you know what happens. When your car is fixed, get right on tht horse again.
