My thoughts are definitely domestic, as I don't see any overseas trip developments happening.
But my dreams:
International:
Azores (Thompson does it so I see this as highly possible, especially now they have a mainland Portugal adventure), Switzerland (entirely- they already have Italy/Switzerland), Belgium, Russia,
Canada (entirely).
Domestic:
Louisiana, Seattle/Oregon, New Mexico, South Dakota (Rushmore), the Carolinas, Boston/Connecticut/Cape Cod, Michigan lakes, Chicago, Tennessee (Nashville/Memphis). Return of reimagined Philadelphia/DC maybe?
