I saw swallows just over a week ago in southern Spain, slowly heading north, I think these ones go to France rather that the UK, the British ones fly over Portugal and up, but it's a good sign.
I've almost got a yearning to go back to the Greek islands now, the last time I went to Crete and thoroughly enjoyed it, though I prefer the smaller, more intimate islands like Serifos, Sifnos, Naxos and Paros.
