Growing up, I had a fascination with hovercraft because they were neither plane nor boat/automobile. Skimming just above surfaces, they mixed the two concepts into an illusion which also had practical benefits: Efficient, speedy transport on water, ice or land.
After building some small working examples, a friend and I ordered the plans out of the back of Popular Science magazine and started a project that would move from basement to garage to bigger garage to lake. Before graduating high school we were able to zoom around on parking lots and grass fields. Once I learned how to weld and use a lathe and milling machine, we were able to upgrade the whole powertrain and venture out onto nearby Owasco lake in Central New York.
