A waist-deep stealth mission against a hushed horizon brings intimate and elemental contact. The moss-covered bottom feels spongy as bubbles of oxygen hiss and pop with each shuffle. The water feels vital, and the near bank flutters and bounces with life-a leopard frog launches with a startled squirt and a slider turtle slants from a log. A displaced blue heron croaks irritably overhead. And, off the point of reeds, the surface humps with the faint promise of a heavy fish.
