WAY TO GO, SAM!

As a long-time orienteer, I was delighted to see that Sam Murphy had tried, and enjoyed, orienteering (RW, May). It’s a great sport, exercising the mind as well as the body. It’s more challenging than a trail race, more fun than a road race and more interesting than an obstacle race. What about an article to tell your readers what it's all about?
