There are hotpots and geysirs in various areas in Iceland. The most famous ones are in an area called Geysir. The name geyser comes from the name geyser in Icelandic originally. While not as big as Old faithful, they are still pretty cool and fun to see. The ground steams and bubbles in many areas.
Dave found a tractor in the visitor's center! No one else wears plaid in Iceland. It was always easy to spot Dave.
