"Chargers," however, are rare. Most bucks come walking or trotting to the clatter of antlers, confident and alert, tails half-raised to the horizontal -- a sure sign that they're completely fooled. Others -- the old, smart ones -- come in like a bobcat stalking a varmint call, sneaking and circling for the wind, using every shred of cover. These often escape notice; they've figured out that the crash-bang of a buck fight isn't always created by a pair of randy bucks. Sometimes they hang up, just like an old gobbler that won't come in and won't go away, and you may need special rattling tactics (see sidebar) to bring them in.
