So sorry to hear of Bob's passing. I remember him fondly during the years he was active here on Ihub. He was way too young to have the thread of his life cut short. But things are as they are and crossing over into the unknown is the natural fate of every living thing. We do not mourn his passing because we know he has moved on to other things -- we mourn for ourselves, for the loss of his presence among us and for that reminder of our own mortality.
