I will pack tons of beef jerky and cashews, and I will sleep in a ditch. :)
Might find a sheep stepping on your face. They run free most places there, and if one jumps in front of you and you hit it it's YOUR fault. All kidding aside it's a very pretty country, almost everyone there speaks english, the thermal features are quite interesting as are the waterfalls and glaciers, but a lot of their roads are unpaved, and you can't get around without a car. It was cheaper than Norway, but almost every place is.
