Please DO NOT TRY this at home...

I am NOT advocating that you climb up into your attic - REALLY, DON'T. I just thought that it might be interesting for you to see what is similar to what's in your attic. It's just a precautionary tale about keeping up with maintenance of your units. once again, PLEASE DO NOT TRY THIS AT HOME. Just think of it as PBS- interesting, but not for you to go out and do with out a license. :)
