Sulu... Again another very thoughtful post. Like you without lots of direct evidence there is circumstantial evidence that one could reasonable conclude "strands 2 and 3" are close and will appear shortly. Sun Tzu commented .. "It is too late to cover your ears after you hear the thunderclap"....we are viewing "the lightning" .. We have been warned.... Soon "the clap" ....If I might be permitted... Our respected colleague Eileen held a similar perspective.. I for one miss her input.... Again thank you Sulasailor for taking the time for an excellent post. Tpower
