Forest Cruise Ship

       N and I were on a cruise, not sure to where. The destination didn't seem to be important, though, as we were having a great time racing through the forests trying to round up buffalo. The cruise ship was a huge forest from bow to stern. There were a couple of circular stair cases around the ship that allowed you to run down below decks to where the regular cruise ship cabins were located, as well as the dining rooms and shops. The entire upper deck of the ship was a forest, though, green and lush, a mix of pines and eldar, ash, birch and elms. I found a couple of oaks and walnut trees as well. I remember thinking that there should be more nut trees if they wanted to cut down on their food bills.
       I wondered if I could build such a ship, and if it could actually support buffalo and people (though certainly not as many as were aboard the ship in the dream.) Sort of a "bioboat" instead of a "biosphere."
