In this part of the country (lightning capital of the universe) I would get the shivers from any of those wired suggestions. I would use something like Barry's suggestion or a local solar panel. But MN isn't FL

Years ago, when we built the house I put in a long run of wire and water pipe out to the "back 40". Hooked up the water, but never got around to the electricity. A few years later , a tree that it passed by was struck. Blew up the pipe and fried the wire. Thankfully my procrastination saved the day. The wire is still there, in pieces...
