At least you had lantern's & fuel, most people can't even find a flashlight, and those that can probably don't have good batterys.
It's a good idea to test the lanterns from time to time as well as flashlights for bad batteries or bulbs. Always keep a supply of wicks,batteries, bulbs etc. handy. Little drills are always good to keep us ready for when it's the real thing, which I believe is just around the corner.
