[That last post was getting kinda long . . .]
I still don't have an adequate water-storage solution (for home or in the vehicles). We live in Los Angeles, earthquake country, so we're all supposed to have some food and water on-hand. But, you're supposed to change out bottled water every six months (or sooner), so that's a bit of a burden to remember. I think we have four gallons of water in the garage. I'm also planning to buy some "emergency food." It's fairly inexpensive and has a shelf life of five years.
Also, I do want to get more space blankets, more magnesium fire-starters (they're only $6.00), and more safety and signaling devices. I've also been meaning to get a multi-tool into the glove compartments of each car (only the van has one right now). I have a $400 Rigid steel toolbox that I'll eventually re-purpose for an emergency food and water container. I'll place that in the backyard so that we can still get to it in case the house collapses.
