I'm working through the "Let other know what locations you are working on" page, trying to get it back up to five unconnected branches per jurisdiction after a whole bunch of the listed branches have been connected. (And a huge thank you to all the people who have put in so much work connecting those branches! You are helping to make WikiTree better and stronger, and you're helping to motivate people who might have been tempted to give up on WikiTree because they were having so much trouble getting connected to the main tree. Having to replenish lists of unconnected people is a wonderful "problem" to have!)
So far, I've made it down to Alaska, and then I ran into a problem. For one thing, Alaska hasn't been part of the United States of America for very long (at least, not compared to most states), and it's not exactly crowded, so there aren't a whole lot of profiles for people who were born in Alaska.
But more importantly, there are a bunch of profiles where the place of birth (or death) is marked as simply "AK", and in an awful lot of those cases, I suspect that the person was actually born (or died) somewhere other than Alaska. I'm not sure, but many of the profiles I've looked into appear to be for people from Arkansas, Oklahoma, or some other place, and the person creating the profile put in "AK" instead of "AR" or "OK" or whatever other two-letter code would apply. (And, yes, I know, they really should have spelled out the name of the state in full, but using the wrong state code made it even worse.)
So if you've been looking for profiles from Arkansas, Oklahoma, or possibly other places, and not finding them, that might be why. You can find open profiles with "AK" in them using this WikiTree+ search.
