I just saw the oddest thing I have ever seen, and I could not bring a camera to bear in time. imagine a small dot, like a very small spider 3 - 4 mm. then a line coming off that spider, extending to 10 mm, with a second spider on it. then the line retracts from the far end, and the cycle repeats itself. by the time I found a camera and got a battery on it, the thing was gone. p.s. in my shack, while building a J pole.
