The forecast helps and there are some bushes and trees, around the edge that move in the wind, but I wanted some thing that would help as the wind moved around while I was down there. It needed to be light weight, cheap, portable and cheap!
So meet the wind direction-o-meter (patent not pending!)...
To the untrained eye it may look like a cable tie with a piece of pink wool attached but this is a high tech piece of equipment!
I'm sure I have seen some videos/pictures with buggys with something similar attached.
