Yep - every 6 months, the LM clan hooks the stereo up to the internet, blasts general conference throughout the house and yard, and dumps all the kits out on the living room floor and goes through everything.

We also: put up/take down the hummingbird feeder (when I remember)
change the water filter
pour all the storage gasoline into our vehicles and store fresh
change batteries in the smoke detectors (we all hate waking up at 3am to one of them chirping their low battery alarm at us)
gas up or winterize the mower and tiller
etc
