I work in the tourism industry and just had a couple of clients come back from Iceland last week. They said they can't describe in words the beauty of this country. They also booked tours there and said that they would have prefered to rent a car rather then depend on a group scheddule. One thing they enjoyed was the free Reykjavick city tours, they said that you could really feel the passion in the way those guides did their job. Your photos are lovely, I will also surely visit Iceland soon :)
