I had three home visits from three departments, all were unannounced. One I was in jeans, one I was in sweats, and the last one (MSP) got me in my running gear heading out the door (he wanted to talk to my wife). You want to be on your best behavior, and do a quick spring cleaning, but be yourself. I think the fact that we had some SEMBLANCE of order in a house w/a 9 yr old daughter, dog, cat, bird, and hamster scored more points than living in a museum piece. (That didn't stop me from running into the head and squarring it away in 15 seconds though!) Good luck.
