One year I had my entire outdoor crop (3lb.) hanging in the attic from some chicken-wire. I was down in the barn when my came running to say the F.D. was on the way. As I ran up the attic stairs I could hear the sirens. The shit was too well tied up so I ripped it down chicken-wire and all, rolled it up, and buried it with shit. On the way down I ran into a firefighter going up. I said "everything's cool up there, I just checked!", but he had to look at the chimney anyway. I went back up and I was glad to see the stuff wasn't visible. After he checked the chimney he said "You should pick up that junk-pile, it's a fire hazard and rodents nest- I can smell it."
"Yeah I will."
When we had the chimney cleaned the Sweep found the smoked mummy of a female mallard duck, who apparently had built a nest and then got trapped and died up there over the summer.
I mean, ya just never know- it's always something.
