I believe the 86 Eldora Nationals was the farthest east I have seen the Tri C Machine. It was when Dave Bradway Jr piloted it. I bought a shirt that week and watched him the following week at Knoxville. One helluva talent and still highly revered on the West coast as the Bradway Memorial is a highly coveted event in NorCal. He was killed the following year at The Dirt Cup at Skagit.
