I'm a car guy, and relatively new to LSR, but as a volunteer at the track I had many conversations and lots of interaction with Dave. He was always helpful, friendly, and understanding, especially to us volunteers. Even more impressive was his willingness to pass along his extraordinary knowledge to any and all at the track. When I have worked staging, many is the time I had seen him passing along suggestions for everything from riding technique to tuning tips to anyone who expressed an interest, and the smart racers were definitely interested. More impressive yet, he clearly had watched the others and had a pretty good idea of what might help.
As Keith said, we really don't have enough information yet to know exactly what happened, but he tells me that ECTA officials will let us all know as we have the facts.
We will always miss him
