Three days ago Norman and Henry from next door learned that I have a Bilderhoos and that it lives on my back porch. They've built with it at every opportunity, and according to their Mom, they talk of little else. Today Henry chose to build a pickup truck, which became a semi-truck, and ended up being some kind of lighthouse tower, with an imaginary glow to guide the sea monsters of Lake Michigan past our rocky shores. Anyway, this video is of the guys on Day 1, when their pal David came over. It contains a surprise.
