As a motorcycle enthusiast it is always sad to hear of someone who pays the ultimate price doing the activity that I so love, but it happens and we learn to move on and cope with it as we know that the activity is dangerous.
As someone who officiates at various race meetings and/or practice days it has always been in the back of my mind that someday I may pay a high price for again doing something that I so love and enjoy.
But to me this seems a senseless tragedy that was (as Jumkie pointed out) likely very avoidable and sadly two people have paid to high a price and are no longer with their families.
Whilst I don't normally get involved or comment in these type of threads, this one touches a very raw nerve and deepest sympathies and condolences to the families of those directly involved, but also thought for thos indirectly affected.
