If you stack too much cycling stuff and other things on the wire racks/shelves in your closet, it will all come tumbling down in the middle of the night and scare the wits out of you...
My shelves were getting there too - and then I found e-Bay! Now I keep the shelves pretty clean. Full bikes, on the other hand, are a problem. I bought a 4-bike rack for storage & put it on my front porch. I just can't bring myself to leave my nice bikes out there though! Now I've got an empty rack on the front porch and bikes in my den.

My wife is of the "this package filled by volume, not by weight" mentality. A space is not full until you can't get the door/drawer/zipper closed after compression is applied. When we moved, I sought out small boxes because whether it's books or pillows, she will fill the box to the top and then tell me where to put it. We have had some close calls with shelves as well.
