SETTING UP TO MEET THE CHALLENGE. First design a train room, then design a house to fit the train room. The design includes a straight shot from the garage down to the train room. That makes a large library possible along the stairwell wall.
It's a library large enough to call for a proper book cart, on which the material for meeting this year's Fifty Book Challenge (and some other material) currently resides. Some of the material will not make the cut to stay in the collection, and it will be off to Half Price Books. Sometimes the stuff that doesn't make my cut commands a pretty good price there. Go figure.
