This seems to be the best place to post this, as, with respect to house maintenance, it seems geeky.

So, the clothes dryer isn't drying. My first instinct is to check the air exhaust. I disconnect the vent from the dryer; sure enough, some stuff is there that I needed to clear out. I hook the vent back up to the dryer and it is drying ok, not perfect. In a couple of days, the laundry room is getting humid. I check the vent and see that it is connected to the dryer, but disconnected from the pipe/vent that is taking it outside. I notice some stuff in that pipe; I put my hand in to clear it, and, it's a nut, and another nut, and another nut, and so on and so on and so on!!! As in nuts that squirrels gather for the winter. Long story short, the entire 5 foot pipe is full of nuts!!! I dismantled it and cleared it; the dryer is working perfectly now.

Although our laundry room is on the 3rd floor, there is some roofing between the 2nd & 3rd floor; the vent comes out just above this roofing. Those pesky squirrels. I'm thinking that some wire cage will be going around the external part of the vent. That round went to me. I've discovered some other things that are squirrel related. I feel like Carl from Caddyshack. This isn't over!!!
