A Weekend in the Sky - Learning to Fly a Bike

An inventor-father realizes his son is eleven years old and still doesn't know how to fly a bicycle! How could he have let this happen?

"Time flies when you're having fun, I suppose." he says.

In that moment, he resolved to ensure his son is an expert bike-flyer by the end of the weekend. After all, it didn't take him too long to learn when he was seven. How hard could it be? Even better, he would be able to fly alongside his son with the new mechanical wings he and his wife had finished recently.

That was the start of a grand weekend out.
