Thanks guys! Interiors are fun and do push the envelope, but sometimes they're an exercise in futility. Case in point: The Hopper house which has details on top of details that no 1:1-sized human will ever see. I guess I have a thing for interiors since I've just built two armor vehicles with full interiors, have an aircraft carrier with a detailed hangar deck, an RAF Hawker Typhoon with a complete engine, and both a Avenger and Corsair which have fully detailed engines, wheel bays, wing fold mechanisms and, in the case of the Avenger, opened up the compartment behind the engine showing its innards. I pick models based on whether they have interiors or not. It wasn't until I sat down and wrote this that it occurred to me how important it is.
Today I got 1/2 of the 2nd level installed. It went reasonably fast… learning curve. Tomorrow I put on the header boards and build the ricks for the second row.
