So was the bird just terribly efficient at construction, or is this a comment on how often the dryer gets used? (Perhaps you hang all your clothes out to dry now that the weather - pretty thunderstorms notwithstanding - is nice.)

Have you heard our chipmunk down the dryer vent/tube stories from our last rental? The one who chewed his way out (plastic tube) snuck up to the kitchen, and freaked both of us out (me and the chipmunk that is) trying to escape! He even had his own cheering section - or panicking relative - another munk clinging to the screen window chittering away while fxz and I ineffectively tried to herd our uninvited guest towards the exit.
