Hubbard, that was two years ago, so I don't remember other than I was checking the net out for what was available at that time.
The problem with the wind whistles is that they may be only effective at over a certain speed,
that's all I can remember.

Around here, you see a deer cross the road, you better beware cause there can be a dozen behind, all crossing one at a time. The young are at the back and get panicky and will cross regardless of traffic. I see them from my deck. Here ther are 12 in the photo going for the road, but there were more.
