1. Vanishing Act: The better you hide your boat—be it a canoe, johnboat, or skiff—the more chances you'll have at squirrels. Sure, you might kill a few with your standard duck-boat setup, but if you're serious about killing a mess of squirrels, commit to fully covering your craft. First, drape camo netting over the gunwales to keep the hull from reflecting morning sunlight. Then, prop up vertical cover—river cane, bamboo, pruned tree branches—in the bow and stern and along the gunwales. Beech branches work great, since they hold brown leaves well into winter, as do evergreen holly boughs. Fine-tune things by visualizing the perspective of a wily, neurotic critter looking down from 30 feet overhead. Don't neglect to camouflage the handles and blades of your paddle, either. Nothing will send a squirrel scurrying away faster than a paddle flash.
