Friends living in the center of France have offered to let me live with them during the winter and spring, if I want. No charge. They don't live at home during the week, so the house is empty, and since they know I'd like to live in France at least part of the year, they offered. I could use the house as a base to go up to Paris, down to Aix-en-Provence, or just a place to hang out, see what it's actually like to live in rural France. Be a quasi-native.
Almost certainly will not happen - little matter of the cost, not to mention that though I would like to be in France, I would not like being away from my wife for an extended period -- but man, that's tempting.
