Though, I haven't taken a good look yet to the possibility of this but how
difficult is it to run cable through an outside wall on a bungalow? It was a
small addition to the kitchen on the back of the house (was there when we
purchased). Below it is a crawlspace and above it is an attic which doesn't
appear to have an access, not even through the main attic space, It's
puzzling as to how I will get in there.

I know it's difficult to answer without seeing, but all suggestions are
appreciated.

Thank you
