I go through our Go Bags every six months or so to rotate food and double check to make sure everything is up to date - and I do it with my car emergency kit at the same time. We use the Time Change as our review time - easy to remember - Rotate the clock, rotate the bags, rotate the car kit, rotate the pantry.
The only thing I really have to do is rotate out the protein packets and update the first aid kit (and double check clothing sizes, but we're pretty stable there) and check batteries. We've never had an emergency where we had to use them, but we have practiced during some extended power outages we've had. I think that helps a lot. Do a practice run for fun one day - and live just off your bag and see what happens
