George: we were in Iceland a few years ago and saw many many greenhouses - heated, I'm sure with the geo-thermal - as most of Iceland is. If you want an interesting and beautiful place to visit, can really recommend iceland. Barb, frantically trying to get ready for our trip to Greece - we leave on the 28th!!!!!
