I am in my late forties. Have played with Lego bricks all of my life. As a child, I loved the Space theme, and the Castle theme. My favorite set was the Airport Shuttle monorail (6399). In 2008, I discovered the Train Engine Shed set (10027). That re-energized my interest. Since, I have been building MOCs across the themes. I am particularly proud of my castles. My son (8 years old) is building with me. His interest is making me discover new Lego themes (particularly Ninjago, Super Mario and Minecraft).
