Just a hill, Brian said, that one morning in New Zealand. He had planned a hike for us. Brian is a climber. He likes big rocks. He likes climbing mountains and volcanoes and is quick and sure footed like a mountain goat. I am a sheep. I like hills. I prefer to meander up them, inspecting flowers, trees and bugs along the way, not really caring if I ever get to the top. But with Brian, I try to keep up as best I can, often herded along by our dog Max.
