Sadly, the Alaska trip is off for this year! Because of some medical issues I'm having, we're staying in the Puget Sound area for a couple of months--but by then it'll be too late to go to Alaska and do it right.
At this point, I haven't even thought about what we could do after treatment is concluded. I'll save the Alaskan notes, but start working on another itinerary to get us back to Arizona with the snowbirds. Let me know if you have any ideas!
