I don't think I have seen anything from the family on this but I am sure it was heart problems.

I think it was in the mid to late nineties he had six way bypass surgery. I read that the doctors said he had three or four years to live after that. They did not realize how tough he was!

I saw Billy quoted that he fought to the very end to stay alive.

Bob was a heavy smoker and while he may have quit eventually I think the continued to smoke after his surgery.

Rip Mr. Glidden.
