From time to time I visit a small park south of my hometown. It’s a fairly average park with a baseball field, a small river, picnic benches and a few miles of paths that meander through the woods. It is those paths that brought me to the park. I like to bring a small lunch and a book and wander from bench to bench. It's a way for someone who spends too much time at a computer to get outside and exercise without being to bored. Not that the park doesn’t bore me. That’s what the book is for. It’s also why I noticed something odd. Not that I really thought much about it at first. It was simply a story I told myself to keep my mind busy, but over time the other explanations began to disappear.
