I don't think I've ever been to an airport without being corralled by something orange and plastic. It seems they're all in a constant state of construction, which is why it's pretty near impossible today to view the spot where JFK arrived that fateful morning in Dallas.
However, if you make your way to the top of Parking Garage B and stand at the east corner, you can at least view the general vicinity.
Somewhere just the other side of the tower seen at the top-right of this photo is gate 28A, now occupied by DHL and inaccessible to the public.
It's that area where President Kennedy disembarked Air Force One, and where he was carried back aboard by pallbearers less than three hours later. It's also the site where Lyndon B. Johnson was sworn in as president, a ceremony commemorated with a plaque that was recently removed from the main lobby.
The plaque is scheduled to be reinstalled in a new flag park — under construction.
