Not really kilt related, Lazurus Long notwithstanding, but I know we have quite a few Heinlein fans on the forum.
I want to let everyone know that the first part of William Patterson’s big 2-volume authorized RAH biography; "Robert A. Heinlein: In Dialogue with His Century: 1907-1948: Learning Curve" came out from TOR Books this week.

I got a copy a while ago, (it's who you know) and it's a very interesting read for the dedicated Heinlein fan.
