My shed is an ex-building site office. Absolutely great. I don't own a caravan, but I do own a folding camper - ready for the off in June to France - the thing is, we don't go to the seaside, we travel everywhere inland - this year its the Loire and Normandy (that's short distance for us). Anyway, what we do, is vist the garden centres there and see what I can pick up. Two years ago, I brought home a vine from Bordeaux - only 2 Euros, and it survived.
