Pink Floyd were sounding like a noisy nightmare. As she gazed out across the valley, with its endless vista of trees, trees and more trees, she came down to earth with a bump. She should get back to work - artificial props might give her a brief respite, but she had a deadline to meet and a quota to make. Sighing, she pressed stop and slipped her headphones down round her neck. Onwards, if not upwards. She stopped and gathered up her equipment - her marking tools, her theodolite. Soon, in a straight line from where she stood, there woukld be a six-lane ribbon of tarmac. How did she feel about that. Suddenly she no longer cared. There were always the butterflies.
