A few nights I needed to make a phone call and reached for the cordless only to have it report that I have no line. WTF! I say to myself. So I check my other phone and no dial tone there. So off to the basement I go, this I hate as I've been struggling with a bat problem and try to avoid going there. Flipping the lights on, I walk over to the phone lines, hear a noise and damned if I don't have a squirrel problem as well. He takes off into another room and I follow along to see a destination. Looking around I notice that the vent flue of my chimney has a gaping hole in it! There is a bullet I've dodged for who knows how long! My carbon monoxide detector has never peeped at all. So after going for a ride today, I'll need to go down into the bowels of my house and work a temporary patch until I can get the furnace guy over to do a proper repair. What I find annoying is that the furnace and flue are not even 10 yrs old and it rusted through the flue. If I didn't like the neighborhood so much, I'd sell cheap and move into the local retirement community!
