Still have all of my stuff in a box. But with N gauge you can put SOOOO much in a small space. His only issue that I recalled him complaining about. He used the "Lifelike" brand of trees n shrubs. Very nice when first placed. But being in the garage, they would dry out and crumble. Though a High School dropout at 11th grade, my Brother was 1,000 times more creative than I'll ever be.
