There's no point having all this kit if you don't know how to use it.
I've seen people superglue their hand to their face, smash themselves in the teeth with a hammer while trying to put up storm shutters, struggle for over an hour trying to start a gasoline generator that didn't have any gas in it, turn an expensive tent into a fireball by attempting to fill a gasoline stove that was already lit, slice their hand open with a screwdriver, and settle down to read the instructions for some essential bit of kit as a storm approaches. Add stress and fear into the mix and you have the potential for a lot of chaos.
Don't be one of those people! Learn to use your kit in comfort, when the lights are on and you have a favorite beverage close at hand. That way, using your kit will become second nature and you won't have to learn how to use it when you're cold, in the dark, or the floodwaters are rising.
Don't, whatever you do, just pack this stuff into a box or store it in the garage until the day you need it!
Use it! Practice your skills!
