Bob was one of those listmembers that gave more than he took.  Always taking time to answer list members questions and even the occasional PMails.  He is missed by many.  I am fortunate to have an engine built by his successor last year and it's currently purring like a kitten.  I keep the Limbo newsletter in my van that has his picture on the cover, it's my motivational shrine that keeps me going when I'm working out there on the van.
