I, like everyone else want to see the DQ in operation as she is now forever.
The current Congress does not seem to see the reason in this. There must be some contingency plan for after.

Could a motion be put forth to declare DQ a Historic Monument and/or National Park? There has to be some public land somewhere along the rivers to moor the boat. The boat could also remain partially operational.

This is the next best option that I see for the boat

1-DQ could become like a National Park Lodge-like Old Faithful Inn
2-Rooms could be rented out, Dining room could be used. Engine room, pilot house could be a museum tour. Calliope concerts could be given. Fees collected would help sustain DQ monument/Park. Ultimately boat could be hauled out of river and put into an enclosure to further protect from elements.

I think that making the boat a Historic Landmark or National Park is in the best interest. MAL could donate it to the Dept of Interior. They would get a tax writoff, Govt would get free boat. The last thing I want to see is some fly by night taking control and letting the boat fall into disrepair and neglect.
