I lived in Anchorage during the heady late 80's - early 90's. There used to be a very large Commodore scene back then - huge! Used to be a commodore/amiga store there, Best Electronics, off of Northern Lights Blvd. There was a very active Amiga group that used to meet in some corporate office building downtown, if I rememeber correctly. They shared the same space as the Mac Users group but in a differnet room on the same evening.
Anyhow, with a little poking around I am sure you will meet a few Amiga folks in Anchorage for sure. I wish I was still there. : )
