Thanks everyone.
We got lucky in that Allegiant has nonstop flights from South Dakota to Orlando on Thursdays and Sundays, and they still have seats left so we got down there Thursday afternoon.
DH and I had been working hard to get the farmhouse cleaned and ready to sell, and got it all done last Sunday - so it was on the market for less than a week, and we had three offers to choose from. And I'd been worried we were asking too much and it would take months and months to sell!
Now I can concentrate on my sewing again - I've not had time to take pictures of the new sewing studio yet.
