It took Dutch immigrants Theo and Jeanne Zoetemelk about four years to get the permits, but they finally have a 40-foot windmill at their home in Norco, California.
Years ago Theo promised his wife he would build her a windmill for her garden. She was happy with the the scale model he made for her.
However, she was surprised when he told her he was planning a full-size version.
With some help from friends, the retired boat builder has finally put up the last sail.
The windmill, a 50th wedding anniversary present, has gears and a generator inside. When fully operational, Theo says it will produce eight kilowatts of electricity.
