I suppose we will not hear any more about the nature of this failure. Guessing here, stuff that
was slid and clamped into place, let go and slid out of place under stress. No slots/slides used
here, just custom drilled round holes.

On the far fringe, got a tiny bit of the devastating CO, NE, SD, MN snow storm. With temps
near freezing, the near vertical arrays stayed clean on their own. The summer tilt array had a
slight bit of snow, which was rapidly disappearing down the snow gaps. Bruce Roe

Thanks a lot. I have applied this technique and it came out really helpful. Most of the snow clears itself, and the left out snow is really easy to clean.
