I could have *sworn* I had written up a ‘US buys Kamchatka’ alternate timeline.

This is seriously weird.  I remember reading about it as a possible change point — basically, there was a small chance that the Imperial Russians could have sold Kamchatka to the USA in the 19th Century — and I was sure that I had done something with the idea.  But I can’t find anything.  Not even a map, and I needed a map.

Does anybody remember me doing something along these lines? I’m kind of at wit’s end on this.  Or I’m getting premature senility.
