@jerksru,
It is nice to learn something more about Thom, beyond the fact that he was involved in that accident, since that was all that most of us really knew about him.
Your description of him as a friendly and very thoughtful man, and "a great person" you worked with for 16 years, is the real legacy he leaves behind--he was someone who was liked and respected and admired. And he was obviously someone who will be missed, and fondly remembered, by the friends, like you, who are now grieving his loss.
The positive memories we leave in the minds and hearts of those who knew us are far more important than any negative comments made by some nitwit on a forum thread
