I have had a wind vane made from an old drum stick and the back of a CD case in my back yard for about 20 years, because I was always surfing and wanted to know which way the wind was blowing ie where the waves would be best and yes it lasted that long. I recently asked one of my tech savvy son's mates which way the wind was blowing and he jumped on the Internet on his phone to find out. I just looked at the stick.
