Wish you luck back there... Checked now, I've been to Teruel and Albarracin, then down the coast to right North of Valencia. The area I know the best is Barcelona, Aragon and over to the West coast via Madrid, it was great roaming around, especially on my own wheels!
Hope to see Spain again, but the way things are going with the whole WEF/WHO/NWO thing I won't count on it...
But I do think about those abandoned villages in the mountains often, such great places to spend some months in defiance! :-)
