And that reinforced a very, very important lesson for me: Look at the landscape. There weren't any trees to be found. The water was gin-clear. And, sure, the trout were blissfully naive to the threats any angler might pose. But I still crawled on my belly to take a look, and, I promise you, when it was time to cast, I never got taller than three feet—it all happened from a kneeling (sometimes prone) position.
