Lil' Hal's Giant Christmas Box

The back story about "Lil Hal's Giant Christmas Box" goes like this. . .
Hal's uncle Clarence had a car repair shop. Hal really loved to watch his uncle at work. But for weeks he was kept away so Hal won't see his uncle's very special project. Clarence had acquired a used race car that needed repairs. The car had a Delco light plant for a motor and used airplane landing tires.

In the meantime, to distract Lil Hal's curiosity, a big box weighted with bricks was wrapped and placed in the attic. His closet had the access stairs to the attic, so he snuck up to the attic for weeks to examine the mystery box.

When Christmas day came, he had the usual gifts under the tree; then he was told he could open the box in the attic. Hal unwrapped several boxes until he found the bricks. There was a note to go to the tree for instructions. there he found he was to follow the string, which leads him through a labyrinth of rooms in his and his grandparents houses and his grandpa's hardware store. The journey ended in the attached garage, where the yellow race car was waiting. What a glorious present for a boy!

A week or so later, his cousin got a turn driving the car, but he ended his trip by crashing into a building. When asked why he crashed the car, he replied, "I didn't know how to stop the car."
But all was well because it was only a small repair to fix the dent.
