Others have mentioned Jack's superb stick 'n tissue skills... His rubber ships were pure artwork. But my fondest memory of him will be his awesome diplomatic skills as a pit boss. He ran the two top circles friction free and without a hitch, ever. Call it the 'duck' theory of contest management. All anybody saw was the duck gliding smoothly across the face of the pond. What they missed was the feet churning away under water to make it look effortless. Jack, Godspeed, my friend. Tom H.
