I am very glad to read that Lu is continuing to improve - keep it up there!
As an avid reader of, and debater with, Lu, ever since his first post on Just Helicopters as "Poonette" (the famous cat, in case you missed that story), I have always enjoyed Lu's stories and reminiscinces of the old days - B47's and S51's. Cool stuff.
You don't get harmony when everybody sings the same note. This is one of the reasons this forum is so much fun.
I hope you are feeling much better, and I look forward to your return to the forum here, Lu.
