A question is whether Port of Portland could get approval, from TSA or one of those, to limo or van transport some transit passengers between flights, to our "two Ikeas" (both near PDX), on the understanding none would bolt, i.e. this is still international airspace but as a convenience we're taking you around.
A precedent for this would be Dum Dum airport that time, Calcutta wide open to Dawn, Alexia and I, even though we had no visas for India. The authorities kept our passports, as guests of the King (Royal Airline owned by the monarch in those days), and we got to tour Victoria Monument and like that. A couple days latter: Shangri-La (Druk-yul), mission accomplished.
The "second Ikea" is our outdoor "EPCOT West", a kind of modeling studio for "exterior solutions" whereas the "first Ikea" (already open for business) is for modeling "interior solutions".
There's an obvious hand-in-glove relationship, as the new exteriors will require interiors, though like I was sharing with Habitat for Humanity, the kitchenettes may come as a unit, from Boeing or whatever, so it's more a matter of customizing on top of that, like in Mobile Home World aka Florida aka Hurricane Alley aka "EPCOT East" (a little slower).
I'm in touch with Helleger & Hickcox about marketing. Even without Port of Portland approval, we could go ahead with regular tourism plans. It's just I expect some of our sponsors will be extra-nationals, possibly round-tripping from Vancouver, BC and not anxious to have their passports stamped with USA insignia.
However, the solution there is simple: Vancouver already hosts USA customs at their site, and you can do rip-out pages, like some Middle Eastern countries do, knowing if you've been to the one, you can't go to the other -- lots of stupid stuff, what expats get used to.
The USA is seen as a mean bully in many parts of the world and it's considered unpatriotic, a sign of moral weakness, to provide any aid in a time of dire need. We'd like to not overly inconvenience our would-be sponsors in that case. Let's be kind to our remaining friends.
