Alaska, is another great idea. Depending on WHERE you go it might even be nice in winter.
I know a few people whom have made the trip there. ALL loved it

Some very good friends of mine made a trip there maybe 10 years ago. rented a 4 whl drive of some sort and drove around the Yukon for about 10 days . Said was one of the best trips he has ever made

My wifes aunt moved to Anchorage back in the mid 70s and never came back

I would love to visit the area someday,,,,,maybe someday I will
