Sphere's and streams in tonight's Good Question. Both Charlotte Young from Cambria and James Kauthen from Santa Maria ask: What are the things that look like basketballs on the power lines leading into Morro Bay. Good Question.
They're called aerial marker balls and warn airplanes about high overhead wires and power lines. They have to be recognizable in all directions from 4000 feet away and alternate in colors, either red and white or orange and white. They're made of light weight aluminum so they don't weigh down the power lines.
The next question comes from Randy Jahr from Arroyo Grande. He asks: how did Arroyo Grande get it's name. In Spanish, Arroyo Grande means big creek or stream. The first historical documents with that name appear in 1842 as a land grant of Rancho Arroyo Grande. the township was established in 1862 and it became a town in 1867. The school district was started before 1871.
