Anna:
Get a generator. I GUARANTEE the power won't go out as long as you can get the generator to start!

But, if you cannot start the generator, you're in for a power loss. This is a variation of Murphy's Law.

See, I have two generators, a big, 6500 watt that's about a zillion years old (older than my teenager by at least a decade). I had a devil of a time getting it running. The teen and I had a plugged petcock, leaking fuel line, leaking fuel bowl and and loose battery (at least it's electric start). We fixed it all. The other generator, a little Honda, took about 10 pulls but started right up (after sitting a few months, 10 pulls is an EASY startup!)

But, by ensuring they both worked, the power company had no excuse to cut us off!
