I have a love/hate relationship with this tab & slot house. It has been a source of joy and pure frustration! And right now I need to do a rehab job because in the 5 years that it sat vacant, it had some "little visitors" that messed up all the carpeting!! eeewwww! And when I went to finally finish the roofing, I realized that I had apparently run out! My goal: finish this beauty by January 1, 2012!
