If I was to speculate, I would be trying to hold this reunion either in Missouri or Nebraska. That way it is almost equal distance for the folks on either coast.
The when would be sometime in 2007, probably in the summer so that those with children who planned to attend wouldn't have to worry about missing any (Though that pre-supposes that their particular school district doesn't go year round).
As to the Clan Moffett idea, it is as good as any. I'm neither for, nor agin it at the moment. The Board is run by a Lee Offutt II. He and I have discussed the possibility, it is plausible, and depending on how the DNA study goes may yet be proven. Time will tell. I know that Lee has a guestbook on his site, I am sure that if you sign it there is a way to let him know that you want to talk.
