Thanks so much! My husband actually knows somebody who is living there but off-base, but he isn't married and doesn't have kids so he doesn't know much about houses, etc. I'd love to live in an English village.
It turns out that our allowance for what we could bring with us is *small*--something like 1/6th of our current possessions--so at least we'd have much less of our stuff if we were living in a smaller house! I imagine we'd probably leave our furniture behind, which would cut way down on the weight (so that we could take more schoolbooks, yay!) to help keep us within limits, and just get something there. I'll have to check out the UK craigslist.
I've also come up with a tentative plan for adjusting our school plans. Our previous plan had us starting U.S. History right around the time that we'd arrive in England. This is obviously not the best plan, since a) it would be really hard to find as many U.S. history books at the library if we weren't in the U.S. and b) we'd be in Europe, so it would be weird to study American history there. So instead, we'll start ancient history as planned, but once ancient history is over, if it looks like we'll be going to England, we'll take a break and do American history while we're still here and in such a ripe place for field trips and such (lots of great Revolutionary War and Civil War locations around here). Then, we'll go back to world history when we hit England. There's a lot of focus on European history and it'll be great to, say, learn about medieval times and then go see a castle or some such, or learn about the Renaissance and then go to the Louvre and see some of the art. My husband will probably try to save up lots of leave so that we can take some trips and go all over Europe while we're over there.
Anyway, it's by no means certain that we'll even have the opportunity, but thanks so much everybody for giving me some ideas about how we can make it work! If you think of anything else, I'd still love to hear it.
