Very shocked to read about this , this morning.
Dan was the the last to come to mind when I was wondering about who could possibly have been involved in the accident. I offer my sincere condolences to Dan's loved ones, 
The Tyco ride was a great chance for Dan, and now it's all gone.
It's a cliche, but I can't think of anything apart from " what a cruel sport"
R.I.P Dan
