Warning, offtopic:

In the middle of the island there is a valley between two volcanoes. AFAIK, there is only one major road there... (or was ~10 years ago when I was there...) How did you get lost in there?

Did you try driving on the top of the Mauna Kea. They said only 4x4 should go there but we drove there with a rental Sunfire... Close to the top the air was so thin that with gas floored it barely made it there... We didn't spent much time there since we didn't want to get mountainsick (terrible headache...). The scenery was strange.. like moon surface?
