One drawback to fishing in the shallows is that fish tend to hang out in some grassy spots. This means that we anglers have to worry about keeping our hooks foul-free or face the chore of defoliating our flies constantly. Depending on whom you talk to, there are several ways to keep a fly "weedless." Actually, a better term would be "mostly weedless" because no method is foolproof, and if it were, it would also be fishless. Tiers use everything from monofilament to wire to special patterns, like bend-backs, all with varying preference and success.
